Subject: bug fix: don't revalidate dropped dentries
X-Git-Url: https://git.fsl.cs.sunysb.edu/?a=commitdiff_plain;h=54c827bd2020c4a97b853eb3634c78652ff93b17;p=unionfs-3.12.y.git

bug fix: don't revalidate dropped dentries

This fixes a harmless but annoying message that unionfs prints if a dropped
dentry is being revalidated, which could happen if you unlink open files.
