| Subject: VFS: fix statfs() automounter semantics regression |
| |
| From: Dan McGee <dpmcgee@gmail.com> |
| |
| commit 5c8a0fbba543d9428a486f0d1282bbcf3cf1d95a upstream. |
| |
| 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. |
