From: John Groves <[email protected]>
This series applies bug fixes (mostly found via sashiko) to the dax/fsdev
series. This has been soaking in the famfs CI pipeline for 2+ weeks and
1) won't affect anything that doesn't use drivers/dax/fsdev.c, and 2)
doesn't affect any known workloads - although the bugs would have
manifested when multi-range DCD dax devices are a thing (soon-ish).
Changes since v1:
* Dropped modes from patch 6 to fs/fuse/famfs.c and
fs/famfs/famfs_inode.c, which are not upstream so it broke
attempts to apply the series. Oops...
* Added patch 7, which addresses a previously-missed review comment
from Jonathan - minor cleanup
