OK... I've just pushed another branch (#for-linus-2) with lock_parent()
change folded into the commit that used to introduce rename_lock-based
variant. Heads of the branches are byte-for-byte identical:
al@duke:~/linux/trees/vfs$ git log vfs/for-linus|head -1
commit ebc6cb92bfeddf25462842f64604bc9fd2aab5b0
al@duke:~/linux/trees/vfs$ git log vfs/for-linus-2|head -1
commit 8cbf74da435d1bd13dbb790f94c7ff67b2fb6af4
al@duke:~/linux/trees/vfs$ git diff ebc6cb92bfeddf25462842f64604bc9fd2aab5b0
8cbf74da435d1bd13dbb790f94c7ff67b2fb6af4
al@duke:~/linux/trees/vfs$
so testing done on one of them obviously applies to another. FWIW, on
#for-linus-2 we have
Shortlog:
Al Viro (6):
lift the "already marked killed" case into shrink_dentry_list()
split dentry_kill()
expand dentry_kill(dentry, 0) in shrink_dentry_list()
shrink_dentry_list(): take parent's ->d_lock earlier
dealing with the rest of shrink_dentry_list() livelock
dentry_kill() doesn't need the second argument now

Linus, how would you prefer it to be handled?
