Umm...  I've got
fs: Handle I_DONTCACHE in iput_final() instead of generic_drop_inode()
and
fs: Kill DCACHE_DONTCACHE dentry even if DCACHE_REFERENCED is set
in "to apply" pile; if that's what you are talking about, I don't
think they are anywhere critical enough for 5.10-final, but I might
be missing something...
