md/raid10: reformat some loops with less indenting.

2011-05-11T04:54:41Z

When a loop ends with an 'if' with a large body, it is neater to make the if 'continue' on the inverse condition, and then the body is indented less. Apply this pattern 3 times, and wrap some other long lines. Signed-off-by: NeilBrown

md/raid10: remove unused variable.

2011-05-11T04:54:32Z

This variable 'disk' is never used - how odd. Signed-off-by: NeilBrown

md/raid10: make more use of 'slot' in raid10d.

2011-05-11T04:54:19Z

Now that we have a 'slot' variable, make better use of it to simplify some code a little. Signed-off-by: NeilBrown

md/raid10: some tidying up in fix_read_error

2011-05-11T04:53:17Z

Currently the rdev on which a read error happened could be removed before we perform the fix_error handling. This requires extra tests for NULL. So delay the rdev_dec_pending call until after the call to fix_read_error so that we can be sure that the rdev still exists. This allows an 'if' clause to be removed so the body gets re-indented back one level. Signed-off-by: NeilBrown

md: simplify raid10 read_balance

2011-05-11T04:27:03Z

raid10 read balance has two different loop for looking through possible devices to chose the best. Collapse those into one loop and generally make the code more readable. Signed-off-by: NeilBrown

md: fix up raid1/raid10 unplugging.

2011-04-18T08:25:43Z

We just need to make sure that an unplug event wakes up the md thread, which is exactly what mddev_check_plugged does. Also remove some plug-related code that is no longer needed. Signed-off-by: NeilBrown

md: use new plugging interface for RAID IO.

2011-04-18T08:25:41Z

md/raid submits a lot of IO from the various raid threads. So adding start/finish plug calls to those so that some plugging happens. Signed-off-by: NeilBrown

Fix common misspellings

block: Require subsystems to explicitly allocate bio_set integrity mempool

2011-03-17T10:11:05Z

MD and DM create a new bio_set for every metadevice. Each bio_set has an integrity mempool attached regardless of whether the metadevice is capable of passing integrity metadata. This is a waste of memory. Instead we defer the allocation decision to MD and DM since we know at metadevice creation time whether integrity passthrough is needed or not. Automatic integrity mempool allocation can then be removed from bioset_create() and we make an explicit integrity allocation for the fs_bio_set. Signed-off-by: Martin K.
