[GIT PULL] vfs fixes

[Christian Brauner]

Hey Linus,

/* Summary */

Here's a few fixes for the current cycle:

- Fix the the buggy conversion of fuse_reverse_inval_entry() introduced
  during the creation rework.

- Disallow nfs delegation requests for directories by setting
  simple_nosetlease().

- Require an opt-in for getting readdir flag bits outside of
  S_DT_MASK set in d_type.

- Fix scheduling delayed writeback work by only scheduling when the
  dirty time expiry interval is non-zero and cancel the delayed work if
  the interval is set to zero.

- Use rounded_jiffies_interval for dirty time work.

- Check the return value of sb_set_blocksize() for romfs.

- Wait for batched folios to be stable in __iomap_get_folio().

- Use private naming for fuse hash size.

- Fix the stale dentry cleanup to prevent a race that causes a UAF.
