  ext4: wipe ext4_dir_entry2 upon file deletion (2021-04-22 16:51:23 -0400)

----------------------------------------------------------------
New features for ext4 this cycle include support for encrypted
casefold, ensure that deleted file names are cleared in directory
blocks by zeroing directory entries when they are unlinked or moved as
part of a hash tree node split.  We also improve the block allocator's
performance on a freshly mounted file system by prefetching block
bitmaps.

There are also the usual cleanups and bug fixes, including fixing a
page cache invalidation race when there is mixed buffered and direct
I/O and the block size is less than page size, and allow the dax flag
to be set and cleared on inline directories.
