Pull exfat updates from Namjae Jeon:
- Fix a remount failure caused by differing process masks by inheriting
the original mount options during the remount process
- Fix a potential divide-by-zero error and system crash in
exfat_allocate_bitmap that occurred when the readahead count was zero
- Add validation for directory cluster bitmap bits to prevent directory
and root cluster from being incorrectly zeroed out on corrupted
images
- Clear the post-EOF page cache when extending a file to prevent stale
mmap data from becoming visible, addressing an generic/363 failure
- Fix a reference count leak in exfat_find by properly releasing the
dentry set in specific error paths
