Subjectbcachefs-for-review
Since last posting: The main change for upstreaming is that I've added deadlock
avoidance code for the page cache coherency lock, and moved all of that code
into fs/bcachefs/ for now - besides adding faults_disabled_mapping to task
struct. See
https://lore.kernel.org/linux-fsdevel/20201111191011.GE3365678@moria.home.lan/

This addresses the last known blocker.

Bcachefs status - not a lot new to report. I've been avoiding making major
changes for awhile and focusing on stabilizing and torture testing, and outside
of erasure coding almost everything is looking pretty solid.

There've been some recent performance improvements - the main one is I changed
the journalling code so that journal writes no longer have to be marked flush +
fua, so now we only issue flush/fua writes when an fsync is done, or when needed
to free up space in the journal, or after a timeout when there's dirty data in
the journal (default 1 second).

Known bugs:
- we see oopses with zstd compression. It looks like if you pass
ZSTD_compressCCtx() a buffer that's not guaranteed to be big enough to fit
the output, it sometimes writes past the end of that buffer.

- erasure coding is not quite stable, something's funky with the management of
our stripes heap, and my erasure coding + device removal test is hanging.

- xfstests generic/547 just started failing after the 5.10 rebase - this is an
fsync issue

- some timestamps bugs - generic/258 started failing after the 5.10 rebase

Aside from that multiple devices, replication, compression, checksumming,
encryption etc. should all be pretty solid - from polling my user base they say
things have stabilized nicely over the past year.

Non fs/bcachefs/ prep patches - bcachefs now depends on some SRCU patches from
Paul McKenney that aren't in yet. Other than that, the list of non fs/bcachefs/
patches has been getting steadily smaller since last posting.

--------

And here's the pull request. It's been rebased and tested on top of 5.10-rc7,
and this is now the master branch that all the bcachefs users have been testing,
not a separate for-review branch:

The following changes since commit 0477e92881850d44910a7e94fc2c46f96faa131f:

Linux 5.10-rc7 (2020-12-06 14:25:12 -0800)
