Subject: [GIT PULL] xfs: fixes for 5.12-rc1

Hi Linus,

Please pull the following branch containing some fixes to the xfs code
for 5.12-rc1.  The most notable fix here prevents premature reuse of
freed metadata blocks, and adding the ability to detect accidental
nested transactions, which are not allowed here.

This branch merges cleanly with upstream as of a few minutes ago.
Please let me know if anything else strange happens during the merge


The following changes since commit 1cd738b13ae9b29e03d6149f0246c61f76e81fcf:

  xfs: consider shutdown in bmapbt cursor delete assert (2021-02-11 08:46:38 -0800)

  xfs: use current->journal_info for detecting transaction recursion (2021-02-25 08:07:04 -0800)

More new code for 5.12:
- Restore a disused sysctl control knob that was inadvertently dropped
  during the merge window to avoid fstests regressions.
- Don't speculatively release freed blocks from the busy list until
  we're actually allocating them, which fixes a rare log recovery
- Don't nest transactions when scanning for free space.
- Add an idiot^Wmaintainer light to detect nested transactions. ;)
