New code for 5.12:

- Fix an ABBA deadlock when renaming files on overlayfs.
- Make sure that we can't overflow the inode extent counters when adding
  to or removing extents from a file.
- Make directory sgid inheritance work the same way as all the other
  filesystems.
- Don't drain the buffer cache on freeze and ro remount, which should
  reduce the amount of time if read-only workloads are continuing
  during the freeze.
- Fix a bug where symlink size isn't reported to the vfs in ecryptfs.
- Disentangle log cleaning from log covering.  This refactoring sets us
  up for future changes to the log, though for now it simply means that
  we can use covering for freezes, and cleaning becomes something we
  only do at unmount.
- Speed up file fsyncs by reducing iolock cycling.
