Description for this pull request:

Browse source 
- 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.
