* [PATCH] blk: Fix SG_IO ioctl failure retry loopingJens Axboe2006-02-081-0/+3
| | | | | | | | | | When issuing an SG_IO ioctl through sd that resulted in an unrecoverable error, a nearly infinite retry loop was discovered. This is due to the fact that the block layer SG_IO code is not setting up rq->retries. This patch also fixes up the sg_scsi_ioctl path.

* [PATCH] move capable() to capability.hRandy.Dunlap2006-01-111-0/+1
| | | | | | | | | | | | | - Move capable() from sched.h to capability.h; - Use <linux/capability.h> where capable() is used (in include/, block/, ipc/, kernel/, a few drivers/, mm/, security/, & sound/; many more drivers/ to go) Signed-off-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [BLOCK] mark some block/ variables consArjan van de Ven2006-01-061-1/+1
| | | | | | | | | the patch below marks various read-only variables in block/* as const, so that gcc can optimize the use of them; eg gcc will replace the use by the value directly now and will even remove the memory usage of these.

| * [SCSI] seperate max_sectors from max_hw_sectorsMike Christie2005-12-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - export __blk_put_request and blk_execute_rq_nowait needed for async REQ_BLOCK_PC requests - seperate max_hw_sectors and max_sectors for block/scsi_ioctl.c and SG_IO bio.c helpers per Jens's last comments. Since block/scsi_ioctl.c SG_IO was already testing against max_sectors and SCSI-ml was setting max_sectors and max_hw_sectors to the same value this does not change any scsi SG_IO behavior. It only prepares ll_rw_blk.c, scsi_ioctl.c and bio.c for when SCSI-ml begins to set a valid max_hw_sectors for all LLDs. Today if a LLD does not set it SCSI-ml sets it to a safe default and some LLDs set it to a artificial low value to overcome memory and feedback issues. Note: Since we now cap max_sectors to BLK_DEF_MAX_SECTORS, which is 1024, drivers that used to call blk_queue_max_sectors with a large value of max_sectors will now see the fs requests capped to BLK_DEF_MAX_SECTORS.

* [BLOCK] Move all core block layer code to new block/ directoryJens Axboe2005-11-041-0/+589
drivers/block/ is right now a mix of core and driver parts. Lets move the core parts to a new top level directory. Al will move the fs/ related block parts to block/ next. Signed-off-by: Jens Axboe <axboe@suse.de>
