Currently ioprio_best function first checks wethere aioprio or bioprio equals IOPRIO_CLASS_NONE (ioprio_valid() macros does that) and if it is so it returns bioprio/aioprio appropriately. Thus the next four lines, that set aclass/bclass to IOPRIO_CLASS_BE, if aclass/bclass == IOPRIO_CLASS_NONE, are never executed. The second problem: if aioprio from class IOPRIO_CLASS_NONE and bioprio from class IOPRIO_CLASS_IDLE are passed to ioprio_best function, it will return IOPRIO_CLASS_IDLE. It means that during __make_request we can merge two requests and set the priority of merged request to IDLE, while one of the initial requests originates from a process with NONE (default) priority. So we can get a situation when a process with default ioprio will experience IO starvation, while there is no process from real-time class in the system. Just removing ioprio_valid check should correct situation. Signed-off-by:

We still need to maintain a private PC style command, since it isn't completely unified with REQ_TYPE_BLOCK_PC yet. Signed-off-by: -

If CONFIG_BUILD_ELF64 was not selected and gcc had -msym32 option (i.e. 4.0 or newer), there is no point to use %highest, %higher for kernel symbols. This patch also fixes 64-bit SMTC version of get_saved_sp() which is broken but harmless since there is no such CPUs for now. A bonus is set_saved_sp() and SMP version of get_saved_sp() are more readable now. Signed-off-by:

Certain gcc versions upto gcc 4.1.1 (probably 4.2-subversion as of 2006-10-10 don't properly change the the predefined symbols if -EB / -EL are used, so we kludge that here. A bug has been filed at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29413. Signed-off-by:

- Calculate a variable in bvec_alloc_bs() only once needed, not earlier (bio.o down from 18408 to 18376 Bytes, 32 Bytes saved, probably due to data locality improvements). - Init variable idx to silence a gcc warning which already existed in the unmodified original base file (bvec_alloc_bs() handles idx correctly, so there's no need for the warning): fs/bio.c: In function `bio_alloc_bioset': fs/bio.c:169: warning: `idx' may be used uninitialized in this function Signed-off-by:
