[BLOCK] Better fix for do_blk_trace_setup() for !CONFIG_BLOCK

2007-10-12T10:50:07+00:00

We don't have the request queue definition, so just make it a
macro instead.

[BLOCK] Fix failing compile with BLK_DEV_IO_TRACE=n

compat_ioctl: handle blk_trace ioctls

2007-10-10T07:26:00+00:00

blk_trace_setup is broken on x86_64 compat systems,
this makes the code work correctly on all 64 bit architectures
in compat mode.

Fix remap handling by blktrace

2007-08-11T20:34:48+00:00

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

[BLOCK] Get rid of request_queue_t typedef

2007-07-24T07:28:11+00:00

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.

[PATCH] blktrace: add timestamp message

2006-12-01T09:39:12+00:00

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).

[PATCH] Split struct request ->flags into two parts

2006-09-30T18:23:37+00:00

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.

[PATCH] Only the first two bits in bio->bi_rw and rq->flags match

2006-07-06T08:18:05+00:00

Not three, as assumed. This causes the barrier bit to be needlessly set
for some IO.

[PATCH] blktrace: readahead support

2006-07-06T08:03:28+00:00

Provide the needed kernel support for distinguishing readahead
from regular read requests when tracing block devices.
