  Several patches touch files outside of our normal purview to set the

libceph: clean up ceph_osdc_start_request prototype

2022-08-03T12:05:39+00:00

This function always returns 0, and ignores the nofail boolean. Drop the
nofail argument, make the function void return and fix up the callers.

rbd: replace usage of found with dedicated list iterator variable

2022-05-25T18:45:13+00:00

To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.

To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean.

This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.

block: remove QUEUE_FLAG_DISCARD

2022-04-18T01:49:59+00:00

Just use a non-zero max_discard_sectors as an indicator for discard
support, similar to what is done for write zeroes.

The only places where needs special attention is the RAID5 driver,
which must clear discard support for security reasons by default,
even if the default stacking rules would allow for it.

block: fix surprise removal for drivers calling blk_set_queue_dying

2022-02-17T14:54:03+00:00

Various block drivers call blk_set_queue_dying to mark a disk as dead due
to surprise removal events, but since commit 8e141f9eb803 that doesn't
work given that the GD_DEAD flag needs to be set to stop I/O.

Replace the driver calls to blk_set_queue_dying with a new (and properly
documented) blk_mark_disk_dead API, and fold blk_set_queue_dying into the
only remaining caller.

Pull ceph updates from Ilya Dryomov:
 "The highlight is the new mount "device" string syntax implemented by
  Venky Shankar. It solves some long-standing issues with using
  different auth entities and/or mounting different CephFS filesystems
  from the same cluster, remounting and also misleading /proc/mounts
  contents. The existing syntax of course remains to be maintained.

  On top of that, there is a couple of fixes for edge cases in quota and
  a new mount option for turning on unbuffered I/O mode globally instead
  of on a per-file basis with ioctl(CEPH_IOC_SYNCIO)"

rbd: make const pointer spaces a static const array

2022-01-13T12:40:06+00:00

Don't populate the const array spaces on the stack but make it static
const and make the pointer an array to remove a dereference. Shrinks
object code a little too.  Also clean up intent, currently it is spaces
and should be a tab.
