[GIT PULL] Btrfs fixes for 5.6-rc3

[David Sterba]

Hi,

there are fixes that were found during testing with help of error
injection, plus some other stable material.

There's a fixup to patch added to rc1 causing locking in wrong context
warnings, tests found one more deadlock scenario. The patches are tagged
for stable, two of them now in the queue but we'd like all three
released at the same time.

I'm not happy about fixes to fixes in such a fast succession namely during
rcs, but I hope we found all the fallouts of 28553fa992cb28be. As the
other fixes are not urgent I'm also fine with delaying the pull until
rc4 and coordinating with stable@.

Thanks.
