2005-11-09Fix AGP compile on non-x86 architecturesLinus Torvalds
AGP shouldn't use "global_flush_tlb()" to flush the AGP mappings, that i spurely an x86'ism. The proper AGP mapping flusher that should be used is "flush_agp_mappings()", which on x86 obviously happens to do a global TLB flush. This makes AGP (or at least the config _I_ happen to use) compile again on ppc64. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

The reply tuple of the PNS->PAC expectation was using the wrong call id. So we had the following situation: - PNS behind NAT firewall - PNS call id requires NATing - PNS->PAC gre packet arrives first then the PNS->PAC expectation is matched, and the other expectation is deleted, but the PAC->PNS gre packets do not match the gre conntrack because the call id is wrong.

2005-11-09[PATCH] md: improve 'scan_mode' and rename it to 'sync_action'NeilBrown
The current sync_action for an array can be one of idle - nothing happening resync - reduncancy being recalcualted recover - missing device being recoverred to spare check - user initiated check of redundancy repair - like resync but user-initiated and ignores bitmap optimisation. Each of these strings can also be written to the 'sync_action' file to cause that action to happen (if appropriate). While 'sync' is not technically correct, as a recovery is *not* a 'sync', I think it is the most servicable word here. Also 'action' is a strong word than 'mode'.

2005-11-09[PATCH] md: split off some md attributes in sysfs to a separate groupNeilBrown
Some, but not all, md array support data redundancy and hence support checking and restoring that redundancy (resync, rebuild). Some attributes apply specifically to functions involving this redundancy, and so should only appear for md arrays for which they are meaningful. i.e. they should not appear for raid0, linear, multpath, faulty. This patch separates these into a distinct group and creates the group only if the personality supports sync_request.

sysfs 1/ I really should be using the __ATTR macros for defining attributes, so that the .owner field get set properly, otherwise modules can be removed while sysfs files are open. This also involves some name changes of _show routines. 2/ Always lock the mddev (against reconfiguration) for all sysfs attribute access. This easily avoid certain races and is completely consistant with other interfaces (ioctl and /proc/mdstat both always lock against reconfiguration). 3/ raid5 attributes must check that the 'conf' structure actually exists (the array could have been stopped while an attribute file was open). 4/ A missing 'kfree' from when the raid5_conf_t was converted to have a kobject embedded, and then converted back again.

2005-11-09[PATCH] md: allow md arrays to be started read-only (module parameter).NeilBrown
When an md array is started, the superblock will be written, and resync may commense. This is not good if you want to be completely read-only as, for example, when preparing to resume from a suspend-to-disk image. So introduce a module parameter "start_ro" which can be set to '1' at boot, at module load, or via /sys/module/md_mod/parameters/start_ro When this is set, new arrays get an 'auto-ro' mode, which disables all internal io (superblock updates, resync, recovery) and is automatically switched to 'rw' when the first write request arrives. The array can be set to true 'ro' mode using 'mdadm -r' before the first write request, or resync can be started without a write using 'mdadm -w'.

2005-11-09[PATCH] md: Remove attempt to use dynamic names in sysfs for component ↵NeilBrown
devices on an MD array. With version-0.90 superblock, component devices on an md device to not have any stable name related to the array -(version-1 assigns a fixed index when a device is added to an array, and this remains despit any hot-swap). The intial code for making these devices appear in sysfs used dynamic names, which would change whenever a hot-spare was swapped for a failed or missing device. This turns out not to be practical in sysfs for a number of reasons. This patch changes then naming of component devices to be based on the result of 'bdevname'. This is stable and should be unique.

2005-11-09[PATCH] md: support BIO_RW_BARRIER for md/raid1NeilBrown
We can only accept BARRIER requests if all slaves handle barriers, and that can, of course, change with time.... So we keep track of whether the whole array seems safe for barriers, and also whether each individual rdev handles barriers. We initially assumes barriers are OK. When writing the superblock we try a barrier, and if that fails, we flag things for no-barriers. This will usually clear the flags fairly quickly. If writing the superblock finds that BIO_RW_BARRIER is -ENOTSUPP, we need to resubmit, so introduce function "md_super_wait" which waits for requests to finish, and retries ENOTSUPP requests without the barrier flag. When writing the real raid1, write requests which were BIO_RW_BARRIER but which aresn't supported need to be retried. So raid1d is enhanced to do this, and when any bio write completes (i.e. no retry needed) we remove it from the r1bio, so that devices needing retry are easy to find. We should hardly ever get -ENOTSUPP errors when writing data to the raid. It should only happen if: 1/ the device used to support BARRIER, but now doesn't. Few devices change like this, though raid1 can! or 2/ the array has no persistent superblock, so there was no opportunity to pre-test for barriers when writing the superblock.
