Merge patch series "Fix two regressions from start_creating()/start_removing() conversion"

Tyler Hicks <code@tyhicks.com> says:

When running the eCryptfs test suite on v6.19-rc2, I noticed BUG splats
from every test and that the umount utility was segfaulting when tearing
down after a test. Bisection led me to commit f046fbb ("ecryptfs:
use new start_creating/start_removing APIs").

This patch series addresses that regression and also a mknod problem
spotted during code review.
