Subject: Unionfs: use int in unionfs_d_revalidate
X-Git-Tag: unionfs-2.1.4~3
X-Git-Url: https://git.fsl.cs.sunysb.edu/?a=commitdiff_plain;h=a3d913b35aea7cf270f098043b20786071279695;p=unionfs-2.6.25.y.git

Unionfs: use int in unionfs_d_revalidate

We have to use an int, even though unionfs_d_revalidate calls other routines
that return only true/false, b/c ->d_revalidate is allowed to return a
negative errno number.
