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: allow O_PATH file descriptors for fstatfs() Olga reported that file descriptors opened with O_PATH do not work with fstatfs(), found during further development of ksh93's thread support. There is no reason to not allow O_PATH file descriptors here (fstatfs is very much a path operation), so use "fdget_raw()". See commit 55815f70147d ("vfs: make O_PATH file descriptors usable for 'fstat()'") for a very similar issue reported for fstat() by the same team.
