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 <[email protected]>
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] 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 <[email protected]>
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 <[email protected]>
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 <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
