Hi,
we have two more fixes for bugs introduced in 4.13. The sector_t problem with
32bit architecture and !LBDAF config seems serious but the number of affected
deployments is hopefully low. The clashing status bits could lead to a
confusing in-memory state of the whole-filesystem operations if used with the
quota override sysfs knob.
Please pull, thanks.
The following changes since commit 8c6c592831a09a28428448e68fb08c6bbb8b9b8b:
btrfs: log csums for all modified extents (2017-09-26 14:54:16 +0200)

On rc3 is possible to observe warning about possible circular locking

Thanks for the report, neither this nor the one you reported on rc2
looks like a deadlock to me.
- %mmap_sem is always 'current->mm->mmap_sem',
- fsync doesn't acquire %mmap_sem, does it?
Not sure why we have a dependency here, tend to be a false one.
thanks,
