Merge tag 'fs_for_v5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull reiserfs updates from Jan Kara:
"The biggest change in this pull is the addition of a deprecation
message about reiserfs with the outlook that we'd eventually be able
to remove it from the kernel. Because it is practically unmaintained
and untested and odd enough that people don't want to bother with it
anymore...
Otherwise there are small udf and ext2 fixes"
* tag 'fs_for_v5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
udf: remove redundant assignment of variable etype
reiserfs: Deprecate reiserfs
ext2: correct max file size computing
reiserfs: get rid of AOP_FLAG_CONT_EXPAND flag
