linux-toradex.git/include/linux/blktrace_api.h, branch v2.6.20.21 Linux kernel for Apalis and Colibri modules [PATCH] blktrace: add timestamp message 2006-12-01T09:39:12+00:00 Olaf Kirch okir@suse.de 2006-12-01T09:39:12+00:00 be1c63411addba3ad750eb4fdfc50b97bc82825e 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 Jens Axboe axboe@suse.de 2006-08-10T06:44:47+00:00 4aff5e2333c9a1609662f2091f55c3f6fffdad36 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.
