Hi Al,
Today's linux-next merge of the vfs tree got a conflict in fs/dcache.c
between commit 98474236f72e ("vfs: make the dentry cache use the lockref
infrastructure") from Linus' tree and commit 590fb51f1cf9 ("vfs: call
d_op->d_prune() before unhashing dentry") from the vfs tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
