Hey Linus,
/* Summary */
This contains a first round of fixes for this cycle:
- Fix the AT_HANDLE_CONNECTABLE option so filesystems that don't know
how to decode a connected non-dir dentry fail the request.
- Use repr(transparent) to ensure identical layout between the C and
Rust implementation of struct file.
- Add a missing xas_pause() into the dax code employing
wait_entry_unlocked_exclusive().
- Fix FOP_DONTCACHE which we disabled for v6.15. A folio could get
redirtied and/or scheduled for writeback after the initial dropbehind
test. Change the test accordingly to handle these cases so we can
re-enable FOP_DONTCACHE again.
This obviously will need backports to v6.15.
/* Testing */
gcc (Debian 14.2.0-19) 14.2.0
