Subject: Unionfs: use igrab instead of atomic_inc inode refcnt
X-Git-Url: https://git.fsl.cs.sunysb.edu/?a=commitdiff_plain;h=41e980356d4cdd74bfa4037647bfda7ebef3652e;p=unionfs-odf.git

Unionfs: use igrab instead of atomic_inc inode refcnt

In branch management code, use igrab() which is better than directly
incrementing the lower inode reference count.
