Take statfs variants to fs/statfs.c Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

fs: reduce the use of module.h wherever possible For files only using THIS_MODULE and/or EXPORT_SYMBOL, map them onto including export.h -- or if the file isn't even using those, then just delete the include. Fix up any implicit include dependencies that were being masked by module.h along the way. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

add f_flags to struct statfs(64) Add a flags field to help glibc implementing statvfs(3) efficiently. We copy the flag values from glibc, and add a new ST_VALID flag to denote that f_flags is implemented. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

pass a struct path to vfs_statfs We'll need the path to implement the flags field for statvfs support. 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. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

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.
