[GIT PULL] block fixes for 7.2-rc4

[Jens Axboe]

Hi Linus,

Fixes for block that should go into this release. This pull request
contains:

- Fixes for the dio bounce buffer helpers: correct the alignment of
  bounced dio read bios to avoid a double unpin, handle huge zero
  folios in bio_free_folios(), and don't warn on the larger-order
  folio attempts in the greedy allocation path.

- Try a slab allocation in bio_alloc_bioset() before falling back to
  the mempool, restoring the previous behavior for non-sleeping
  allocations from a cache-enabled bioset.

- Serialize elevator changes for the same queue using the writer lock.

- Fix a race in blk_time_get_ns() where a task preempted between
  setting PF_BLOCK_TS and the cached-timestamp reload could return 0.

- blk-cgroup fix for leaks and the online flag on a radix_tree_insert()
  failure in blkg_create().

- Free the copied pages when blk_rq_map_kern() fails after
  blk_rq_append_bio() rejects the bio.

- Remove manually added partitions on loop device detach, fixing dead
  partition devices left behind and a subsequent LOOP_CONFIGURE -EBUSY

- Bound the AIX partition lvd scan to the sector that was actually
  read.

- Show the block operation in error injection rules (Jackie)

Please pull!
