2007-10-12[BLOCK] Better fix for do_blk_trace_setup() for !CONFIG_BLOCKJens Axboe1-6/+1
We don't have the request queue definition, so just make it a macro instead. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-11[BLOCK] Fix failing compile with BLK_DEV_IO_TRACE=nBoaz Harrosh1-1/+6
I get a compilation error in sglist-arch branch with BLK_DEV_IO_TRACE=n: CC block/compat_ioctl.o /usr0/export/dev/bharrosh/git/pub/linux-2.6-block/block/compat_ioctl.c: In function ?compat_blk_trace_setup?: /usr0/export/dev/bharrosh/git/pub/linux-2.6-block/block/compat_ioctl.c:568: error: expected expression before ?do? make[2]: *** [block/compat_ioctl.o] Error 1 Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-10compat_ioctl: handle blk_trace ioctlsArnd Bergmann1-1/+6
blk_trace_setup is broken on x86_64 compat systems, this makes the code work correctly on all 64 bit architectures in compat mode. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-08-11Fix remap handling by blktraceAlan D. Brunelle1-1/+2
This patch provides more information concerning REMAP operations on block IOs. The additional information provides clearer details at the user level, and supports post-processing analysis in btt. o Adds in partition remaps on the same device. o Fixed up the remap information in DM to be in the right order o Sent up mapped-from and mapped-to device information Signed-off-by: Alan D.

2007-07-24[BLOCK] Get rid of request_queue_t typedefJens Axboe1-1/+1
Some of the code has been gradually transitioned to using the proper struct request_queue, but there's lots left. So do a full sweet of the kernel and get rid of this typedef and replace its uses with the proper type. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2006-12-01[PATCH] blktrace: add timestamp messageOlaf Kirch1-0/+12
This adds a new timestamp message to blktrace, giving the timeofday when we starting tracing. This helps user space correlate block trace events with eg an application strace. This requires a (compatible) update to blkparse. The changed blkparse is still able to process traces generated by older kernels, and older versions of blkparse should silently ignore the new records (because they have a pid of 0).

2006-09-30[PATCH] blktrace: support for logging metadata readsJens Axboe1-0/+1
Signed-off-by: Jens Axboe <axboe@suse.de>
2006-09-30[PATCH] Split struct request ->flags into two partsJens Axboe1-1/+1
Right now ->flags is a bit of a mess: some are request types, and others are just modifiers. Clean this up by splitting it into ->cmd_type and ->cmd_flags. This allows introduction of generic Linux block message types, useful for sending generic Linux commands to block devices. Signed-off-by: Jens Axboe <axboe@suse.de>
2006-07-06[PATCH] Only the first two bits in bio->bi_rw and rq->flags matchJens Axboe1-1/+1
Not three, as assumed. This causes the barrier bit to be needlessly set for some IO. Signed-off-by: Jens Axboe <axboe@suse.de>
2006-07-06[PATCH] blktrace: readahead supportNathan Scott1-0/+1
Provide the needed kernel support for distinguishing readahead from regular read requests when tracing block devices. Signed-off-by: Nathan Scott <nathans@sgi.com> Signed-off-by: Jens Axboe <axboe@suse.de>
2006-07-06[PATCH] blktrace: fix barrier vs sync typoNathan Scott1-1/+1
