If you enable +SLUB then everything should work the same (Note the word "should". +There is likely not much value in that word at this point). + +The basic philosophy of SLUB is very different from SLAB. SLAB +requires rebuilding the kernel to activate debug options for all +SLABS. SLUB always includes full debugging but its off by default. +SLUB can enable debugging only for selected slabs in order to avoid +an impact on overall system performance which may make a bug more +difficult to find. + +In order to switch debugging on one can add a option "slub_debug" +to the kernel command line. That will enable full debugging for +all slabs. + +Typically one would then use the "slabinfo" command to get statistical +data and perform operation on the slabs. By default slabinfo only lists +slabs that have data in them. See "slabinfo -h" for more options when +running the command. slabinfo can be compiled with + +gcc -o slabinfo Documentation/vm/slabinfo.c + +Some of the modes of operation of slabinfo require that slub debugging +be enabled on the command line. F.e. no tracking information will be +available without debugging on and validation can only partially +be performed if debugging was not switched on. + +Some more sophisticated uses of slub_debug: +------------------------------------------- + +Parameters may be given to slub_debug. If none is specified then full +debugging is enabled. Format: + +slub_debug=<Debug-Options> Enable options for all slabs +slub_debug=<Debug-Options>,<slab name> + Enable options only for select slabs + +Possible debug options are + F Sanity checks on (enables SLAB_DEBUG_FREE. Sorry + SLAB legacy issues) + Z Red zoning + P Poisoning (object and padding) + U User tracking (free and alloc) + T Trace (please only use on single slabs) + +F.e. in order to boot just with sanity checks and red zoning one would specify: + + slub_debug=FZ + +Trying to find an issue in the dentry cache? Try + + slub_debug=,dentry_cache + +to only enable debugging on the dentry cache. + +Red zoning and tracking may realign the slab. We can just apply sanity checks +to the dentry cache with + + slub_debug=F,dentry_cache + +In case you forgot to enable debugging on the kernel command line: It is +possible to enable debugging manually when the kernel is up. Look at the +contents of: + +/sys/slab/<slab name>/ + +Look at the writable files. Writing 1 to them will enable the +corresponding debug option. All options can be set on a slab that does +not contain objects. If the slab already contains objects then sanity checks +and tracing may only be enabled. The other options may cause the realignment +of objects. + +Careful with tracing: It may spew out lots of information and never stop if +used on the wrong slab. + +SLAB Merging +------------ + +If no debugging is specified then SLUB may merge similar slabs together +in order to reduce overhead and increase cache hotness of objects. +slabinfo -a displays which slabs were merged together. + +Getting more performance +------------------------ + +To some degree SLUB's performance is limited by the need to take the +list_lock once in a while to deal with partial slabs. That overhead is +governed by the order of the allocation for each slab. The allocations +can be influenced by kernel parameters: + +slub_min_objects=x (default 8) +slub_min_order=x (default 0) +slub_max_order=x (default 4) + +slub_min_objects allows to specify how many objects must at least fit +into one slab in order for the allocation order to be acceptable. +In general slub will be able to perform this number of allocations +on a slab without consulting centralized resources (list_lock) where +contention may occur. + +slub_min_order specifies a minim order of slabs. A similar effect like +slub_min_objects. + +slub_max_order specified the order at which slub_min_objects should no +longer be checked. This is useful to avoid SLUB trying to generate +super large order pages to fit slub_min_objects of a slab cache with +large object sizes into one high order page. + + +Christoph Lameter, <clameter@sgi.com>, April 10, 2007 diff --git a/MAINTAINERS b/MAINTAINERS index 0492dd88e12..6d665ac13f9 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -700,6 +700,44 @@ P: Richard Purdie M: rpurdie@rpsys.net S: Maintained +BLACKFIN ARCHITECTURE +P: Aubrey Li +M: aubrey.li@analog.com +P: Bernd Schmidt +M: bernd.schmidt@analog.com +P: Bryan Wu +M: bryan.wu@analog.com +P: Grace Pan +M: grace.pan@analog.com +P: Michael Hennerich +M: michael.hennerich@analog.com +P: Mike Frysinger +M: michael.frysinger@analog.com +P: Jane Lv +M: jane.lv@analog.com +P: Jerry Zeng +M: jerry.zeng@analog.com +P: Jie Zhang +M: jie.zhang@analog.com +P: Robin Getz +M: robin.getz@analog.com +P: Roy Huang +M: roy.huang@analog.com +P: Sonic Zhang +M: sonic.zhang@analog.com +P: Yi Li +M: yi.li@analog.com +L: uclinux-dist-devel@blackfin.uclinux.org +W: http://blackfin.uclinux.org +S: Supported + +BLACKFIN SERIAL DRIVER +P: Aubrey Li +M: aubrey.li@analog.com +L: uclinux-dist-devel@blackfin.uclinux.org +W: http://blackfin.uclinux.org +S: Supported + BAYCOM/HDLCDRV DRIVERS FOR AX.25 P: Thomas Sailer M: t.sailer@alumni.ethz.ch diff --git a/arch/alpha/boot/bootpz.c b/arch/alpha/boot/bootpz.c index 4307bde80a3..1036b515e20 100644 --- a/arch/alpha/boot/bootpz.c +++ b/arch/alpha/boot/bootpz.c @@ -467,3 +467,9 @@ start_kernel(void) #endif runkernel(); } + + /* dummy function, should never be called. */ +void *__kmalloc(size_t size, gfp_t flags) +{ + return (void *)NULL; +} diff --git a/arch/alpha/boot/tools/objstrip.c b/arch/alpha/boot/tools/objstrip.c index 67beb1b45e4..96154e768a2 100644 --- a/arch/alpha/boot/tools/objstrip.c +++ b/arch/alpha/boot/tools/objstrip.c @@ -25,7 +25,6 @@ #include <linux/a.out.h> #include <linux/coff.h> #include <linux/param.h> -#include <linux/string.h> #ifdef __ELF__ # include <linux/elf.h> #endif diff --git a/arch/alpha/kernel/osf_sys.c b/arch/alpha/kernel/osf_sys.c index be133f1f75a..ea405f5713c 100644 --- a/arch/alpha/kernel/osf_sys.c +++ b/arch/alpha/kernel/osf_sys.c @@ -93,7 +93,6 @@ osf_set_program_attributes(unsigned long text_start, unsigned long text_len, * offset differences aren't the same as "d_reclen"). */ #define NAME_OFFSET offsetof (struct osf_dirent, d_name) -#define ROUND_UP(x) (((x)+3) & ~3) struct osf_dirent { unsigned int d_ino; @@ -115,7 +114,7 @@ osf_filldir(void *__buf, const char *name, int namlen, loff_t offset, { struct osf_dirent __user *dirent; struct osf_dirent_callback *buf = (struct osf_dirent_callback *) __buf; - unsigned int reclen = ROUND_UP(NAME_OFFSET + namlen + 1); + unsigned int reclen = ALIGN(NAME_OFFSET + namlen + 1, sizeof(u32)); unsigned int d_ino; buf->error = -EINVAL; /* only used if we fail */ @@ -174,7 +173,6 @@ osf_getdirentries(unsigned int fd, struct osf_dirent __user *dirent, return error; } -#undef ROUND_UP #undef NAME_OFFSET asmlinkage unsigned long @@ -1267,6 +1265,9 @@ arch_get_unmapped_area(struct file *filp, unsigned long addr, if (len > limit) return -ENOMEM; + if (flags & MAP_FIXED) + return addr; + /* First, see if the given suggestion fits.

This can easily be troublesome if userspace disables + * one event (say periodic) and then right after enables an event (say alarm). + * Since all events are maintained in the same interrupt mask register, if + * we wrote to it to disable the first event and then wrote to it again to + * enable the second event, that second event would not be enabled as the + * write would be discarded and things quickly fall apart. + * + * To keep this delay from significantly degrading performance (we, in theory, + * would have to sleep for up to 1 second everytime we wanted to write a + * register), we only check the write pending status before we start to issue + * a new write. We bank on the idea that it doesnt matter when the sync + * happens so long as we don't attempt another write before it does.

Directly after this is a copy of the task_struct, which + is currently not used by gdb, but it may come in useful at some point. + All of the registers are stored as part of the upage.

All of the addresses are rounded in such a way that an integral + number of pages is written. + STACK: We need the stack information in order to get a meaningful + backtrace.
