From: Dan McGee Date: Tue, 1 Nov 2011 23:23:10 +0000 (-0500) Subject: VFS: fix statfs() automounter semantics regression X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=5c8a0fbba543d9428a486f0d1282bbcf3cf1d95a;p=~shefty%2Frdma-dev.git VFS: fix statfs() automounter semantics regression No one in their right mind would expect statfs() to not work on a automounter managed mount point. Fix it. [ I'm not sure about the "no one in their right mind" part. It's not mounted, and you didn't ask for it to be mounted. But nobody will really care, and this probably makes it match previous semantics, so.. - Linus ] This mirrors the fix made to the quota code in 815d405ceff0d69646.
