VFS: fix statfs() automounter semantics regression 2011-11-05T01:15:59+00:00 Dan McGee dpmcgee@gmail.com 2011-11-01T23:23:10+00:00 5c8a0fbba543d9428a486f0d1282bbcf3cf1d95a 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.

clean statfs-like syscalls up 2011-03-14T13:15:28+00:00 Al Viro viro@zeniv.linux.org.uk 2011-03-12T15:41:39+00:00 c8b91accfa1059d5565443193d89572eca2f5dd6 New helpers: user_statfs() and fd_statfs(), taking userland pathname and descriptor resp. and filling struct kstatfs.

We do have it available in all callers except: - ecryptfs_statfs. This one doesn't actually need vfs_statfs but just needs to do a caller to the lower filesystem statfs method. - sys_ustat. Add a non-exported statfs_by_dentry helper for it which doesn't won't be able to fill out the flags field later on. In addition rename the helpers for statfs vs fstatfs to do_*statfs instead of the misleading vfs prefix.
