2009-09-11net: Add DEVTYPE support for Ethernet based devicesMarcel Holtmann
The Ethernet framing is used for a lot of devices these days. Most prominent are WiFi and WiMAX based devices. However for userspace application it is important to classify these devices correctly and not only see them as Ethernet devices. The daemons like HAL, DeviceKit or even NetworkManager with udev support tries to do the classification in userspace with a lot trickery and extra system calls. This is not good and actually reaches its limitations. Especially since the kernel does know the type of the Ethernet device it is pretty stupid. To solve this problem the underlying device type needs to be set and then the value will be exported as DEVTYPE via uevents and available within udev. # cat /sys/class/net/wlan0/uevent DEVTYPE=wlan INTERFACE=wlan0 IFINDEX=5 This is similar to subsystems like USB and SCSI that distinguish between hosts, devices, disks, partitions etc. The new SET_NETDEV_DEVTYPE() is a convenience helper to set the actual device type. All device types are free form, but for convenience the same strings as used with RFKILL are choosen. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: David S.

2009-09-11tracing: move tgid out of generic entry and into userstackSteven Rostedt

2009-09-11block: add blk-iopoll, a NAPI like approach for block devicesJens Axboe
This borrows some code from NAPI and implements a polled completion mode for block devices. The idea is the same as NAPI - instead of doing the command completion when the irq occurs, schedule a dedicated softirq in the hopes that we will complete more IO when the iopoll handler is invoked. Devices have a budget of commands assigned, and will stay in polled mode as long as they continue to consume their budget from the iopoll softirq handler. If they do not, the device is set back to interrupt completion mode. This patch holds the core bits for blk-iopoll, device driver support sold separately.

2009-09-11block: improve queue_should_plug() by looking at IO depthsJens Axboe
Instead of just checking whether this device uses block layer tagging, we can improve the detection by looking at the maximum queue depth it has reached.

2009-09-11block: implement mixed merge of different failfast requestsTejun Heo
Failfast has characteristics from other attributes. When issuing, executing and successuflly completing requests, failfast doesn't make any difference. It only affects how a request is handled on failure. Allowing requests with different failfast settings to be merged cause normal IOs to fail prematurely while not allowing has performance penalties as failfast is used for read aheads which are likely to be located near in-flight or to-be-issued normal IOs. This patch introduces the concept of 'mixed merge'. A request is a mixed merge if it is merge of segments which require different handling on failure. Currently the only mixable attributes are failfast ones (or lack thereof). When a bio with different failfast settings is added to an existing request or requests of different failfast settings are merged, the merged request is marked mixed. Each bio carries failfast settings and the request always tracks failfast state of the first bio. When the request fails, blk_rq_err_bytes() can be used to determine how many bytes can be safely failed without crossing into an area which requires further retrials. This allows request merging regardless of failfast settings while keeping the failure handling correct. This patch only implements mixed merge but doesn't enable it. The next one will update SCSI to make use of mixed merge. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Niel Lambrechts <niel.lambrechts@gmail.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2009-09-11block: use the same failfast bits for bio and requestTejun Heo
bio and request use the same set of failfast bits. This patch makes the following changes to simplify things. * enumify BIO_RW* bits and reorder bits such that BIOS_RW_FAILFAST_* bits coincide with __REQ_FAILFAST_* bits. * The above pushes BIO_RW_AHEAD out of sync with __REQ_FAILFAST_DEV but the matching is useless anyway. init_request_from_bio() is responsible for setting FAILFAST bits on FS requests and non-FS requests never use BIO_RW_AHEAD. Drop the code and comment from blk_rq_bio_prep(). * Define REQ_FAILFAST_MASK which is OR of all FAILFAST bits and simplify FAILFAST flags handling in init_request_from_bio().

2009-09-11writeback: switch to per-bdi threads for flushing dataJens Axboe
This gets rid of pdflush for bdi writeout and kupdated style cleaning. pdflush writeout suffers from lack of locality and also requires more threads to handle the same workload, since it has to work in a non-blocking fashion against each queue. This also introduces lumpy behaviour and potential request starvation, since pdflush can be starved for queue access if others are accessing it. A sample ffsb workload that does random writes to files is about 8% faster here on a simple SATA drive during the benchmark phase. File layout also seems a LOT more smooth in vmstat: r b swpd free buff cache si so bi bo in cs us sy id wa 0 1 0 608848 2652 375372 0 0 0 71024 604 24 1 10 48 42 0 1 0 549644 2712 433736 0 0 0 60692 505 27 1 8 48 44 1 0 0 476928 2784 505192 0 0 4 29540 553 24 0 9 53 37 0 1 0 457972 2808 524008 0 0 0 54876 331 16 0 4 38 58 0 1 0 366128 2928 614284 0 0 4 92168 710 58 0 13 53 34 0 1 0 295092 3000 684140 0 0 0 62924 572 23 0 9 53 37 0 1 0 236592 3064 741704 0 0 4 58256 523 17 0 8 48 44 0 1 0 165608 3132 811464 0 0 0 57460 560 21 0 8 54 38 0 1 0 102952 3200 873164 0 0 4 74748 540 29 1 10 48 41 0 1 0 48604 3252 926472 0 0 0 53248 469 29 0 7 47 45 where vanilla tends to fluctuate a lot in the creation phase: r b swpd free buff cache si so bi bo in cs us sy id wa 1 1 0 678716 5792 303380 0 0 0 74064 565 50 1 11 52 36 1 0 0 662488 5864 319396 0 0 4 352 302 329 0 2 47 51 0 1 0 599312 5924 381468 0 0 0 78164 516 55 0 9 51 40 0 1 0 519952 6008 459516 0 0 4 78156 622 56 1 11 52 37 1 1 0 436640 6092 541632 0 0 0 82244 622 54 0 11 48 41 0 1 0 436640 6092 541660 0 0 0 8 152 39 0 0 51 49 0 1 0 332224 6200 644252 0 0 4 102800 728 46 1 13 49 36 1 0 0 274492 6260 701056 0 0 4 12328 459 49 0 7 50 43 0 1 0 211220 6324 763356 0 0 0 106940 515 37 1 10 51 39 1 0 0 160412 6376 813468 0 0 0 8224 415 43 0 6 49 45 1 1 0 85980 6452 886556 0 0 4 113516 575 39 1 11 54 34 0 2 0 85968 6452 886620 0 0 0 1640 158 211 0 0 46 54 A 10 disk test with btrfs performs 26% faster with per-bdi flushing.

2009-09-10[SCSI] libfc: send GPN_ID in reaction to single-port RSCNs.Joe Eykholt
When an RSCN indicates changes to individual remote ports, don't blindly log them out and then back in. Instead, determine whether they're still in the directory, by doing GPN_ID. If that is successful, call login, which will send ADISC and reverify, otherwise, call logoff. Perhaps we should just delete the rport, not send LOGO, but it seems safer. Also, fix a possible issue where if a mix of records in the RSCN cause us to queue disc_ports for disc_single and then we decide to do full rediscovery, we leak memory for those disc_ports queued. So, go through the list of disc_ports even if doing full discovery. Free the disc_ports in any case. If any of the disc_single() calls return error, do a full discovery. The ability to fill in GPN_ID requests was added to fc_ct_fill(). For this, it needs the FC_ID to be passed in as an arg. The did parameter for fc_elsct_send() is used for that, since the actual D_DID will always be 0xfffffc for all CT requests so far.

This is less disruptive after fabric changes that don't affect the state of the target. Implement the sending of ADISC via fc_els_fill. Add ADISC state to the rport state machine.

2009-09-10[SCSI] libfc: make rport structure optionalJoe Eykholt
Allow a struct fc_rport_priv to have no fc_rport associated with it. This sets up to remove the need for "rogue" rports. Add a few fields to fc_rport_priv that are needed before the fc_rport is created. These are the ids, maxframe_size, classes, and rport pointer. Remove the macro PRIV_TO_RPORT(). Just use rdata->rport where appropriate. To take the place of the get_device()/put_device ops that were used to hold both the rport and rdata, add a reference count to rdata structures using kref. When kref_get decrements the refcount to zero, a new template function releasing the rdata should be called. This will take care of freeing the rdata and releasing the hold on the rport (for now). After subsequent patches make the rport truly optional, this release function will simply free the rdata. Remove the simple inline function fc_rport_set_name(), which becomes semanticly ambiguous otherwise. The caller will set the port_name and node_name in the rdata->Ids, which will later be copied to the rport when it its created.

2009-09-10[SCSI] libfc: change elsct to use FC_ID instead of rdataJoe Eykholt
tt.elsct_send is used by both FCP and by the rport state machine. After further patches, these two modules will use different structures for the remote port. So, change elsct_send to use the FC_ID instead of the fc_rport_priv as its argument. It currently only uses the FC_ID anyway. For CT requests the destination FC_ID is still implicitly 0xfffffc. After further patches the did arg on CT requests will be used to specify the FC_ID being inquired about for GPN_ID or other queries.

2009-09-10[SCSI] libfc: make fc_rport_priv the primary rport interface.Joe Eykholt
The rport and discovery modules deal with remote ports before fc_remote_port_add() can be done, because the full set of rport identifiers is not known at early stages. In preparation for splitting the fc_rport/fc_rport_priv allocation, make fc_rport_priv the primary interface for the remote port and discovery engines. The FCP / SCSI layers still deal with fc_rport and fc_rport_libfc_priv, however.

2009-09-10[SCSI] libfc: fix RPORT_TO_PRIV and PRIV_TO_RPORT() macros.Joe Eykholt
These macros introduce extra undesirable semicolons that keep them from being used in expressions, and they don't protect against being passed an expression. Add parens and remove the semicolons.

2009-09-10[SCSI] libfc: change interface for rport_createJoe Eykholt
The interface for lport->tt.rport_create() takes a fc_disc_port arg, which is unnatural for most calls. The only reason for this was to avoid passing in the local port as an argument, but otherwise added to complexity. Simplify by just using lport and fc_rport_identifiers.

2009-09-10[SCSI] libfc: prepare to split off struct fc_rport_priv from fc_rport_libfc_privJoe Eykholt
While the I/O and LLD interfaces use fc_rport_libfc_priv, the disc and rport interfaces will use fc_rport_priv, which will be separately allocated. Change the disc and rport usage of fc_rport_libfc_priv to fc_rport_priv. Use #define temporarily to make both names equivalent until a subsequent patch splits them.
