Pull ceph updates from Ilya Dryomov:
"On the filesystem side we have:
- a fix to enforce quotas set above the mount point (Luis Henriques)
- support for exporting snapshots through NFS (Zheng Yan)
- proper statx implementation (Jeff Layton). statx flags are mapped
to MDS caps, with AT_STATX_{DONT,FORCE}_SYNC taken into account.
- some follow-up dentry name handling fixes, in particular
elimination of our hand-rolled helper and the switch to __getname()
as suggested by Al (Jeff Layton)
- a set of MDS client cleanups in preparation for async MDS requests
in the future (Jeff Layton)
- a fix to sync the filesystem before remounting (Jeff Layton)
On the rbd side, work is on-going on object-map and fast-diff image
features"

Pull Wimplicit-fallthrough updates from Gustavo A. R. Silva:
"Mark switch cases where we are expecting to fall through.
This is part of the ongoing efforts to enable -Wimplicit-fallthrough.
Most of them have been baking in linux-next for a whole development
cycle. And with Stephen Rothwell's help, we've had linux-next
nag-emails going out for newly introduced code that triggers
-Wimplicit-fallthrough to avoid gaining more of these cases while we
work to remove the ones that are already present.
We are getting close to completing this work. Currently, there are
only 32 of 2311 of these cases left to be addressed in linux-next. I'm
auditing every case; I take a look into the code and analyze it in
order to determine if I'm dealing with an actual bug or a false
positive, as explained here:
https://lore.kernel.org/lkml/c2fad584-1705-a5f2-d63c-824e9b96cf50@embeddedor.com/
While working on this, I've found and fixed the several missing
break/return bugs, some of them introduced more than 5 years ago.
Once this work is finished, we'll be able to universally enable
"-Wimplicit-fallthrough" to avoid any of these kinds of bugs from
entering the kernel again"

xfstest generic/452 was triggering a "Busy inodes after umount" warning. ceph was allowing the mount to go read-only without first flushing out dirty inodes in the cache. Ensure we sync out the filesystem before allowing a remount to proceed.

GCC9 is throwing a lot of warnings about unaligned accesses by callers of ceph_pr_addr. All of the current callers are passing a pointer to the sockaddr inside struct ceph_entity_addr. Fix it to take a pointer to a struct ceph_entity_addr instead, and then have the function make a copy of the sockaddr before printing it.

I originally thought there was a potential race here, but the fact that this is called with the mdsc->mutex held, ensures that the last reference to the session can't be put here. Still, it's clearer to just return the value from get_session here, and may prevent a bug later if we ever rework this code to be less reliant on mutexes.
