Corrections in Documentation/block/ioprio.txt

2007-10-10T07:25:57+00:00

The newer glibc does not allow system calls to be made via _syscallN()
wrapper. They have to be made through syscall(). The ionice code used
the older interface. Correcting it to use syscall.

Introduce rq_for_each_segment replacing rq_for_each_bio

2007-10-10T07:25:56+00:00

Every usage of rq_for_each_bio wraps a usage of
bio_for_each_segment, so these can be combined into
rq_for_each_segment.

We define "struct req_iterator" to hold the 'bio' and 'index' that
are needed for the double iteration.

[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.

Documentation/block/barrier.txt is not in sync with the actual code: - blk_queue_ordered() no longer has a gfp_mask parameter - blk_queue_ordered_locked() no longer exists - sd_prepare_flush() looks slightly different

genhd: expose AN to user space

2007-05-24T03:14:11+00:00

Allow user space to determine if a disk supports Asynchronous Notification of
media changes.  This is done by adding a new sysfs file "capability_flags",
which is documented in (insert file name).  This sysfs file will export all
disk capabilities flags to user space.  We also define a new flag to define
the media change notification capability.
