vfs: allow O_PATH file descriptors for fstatfs()

2013-10-12T20:12:31Z

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.

fs: reduce the use of module.h wherever possible

2012-02-29T00:31:58Z

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

VFS: fix statfs() automounter semantics regression

2011-11-05T01:15:59Z

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

2011-03-14T13:15:28Z

New helpers: user_statfs() and fd_statfs(), taking userland pathname and descriptor resp. and filling struct kstatfs. Syscalls of statfs family (native, compat and foreign - osf and hpux on alpha and parisc resp.) switched to those. Removes some boilerplate code, simplifies cleanup on errors...

add f_flags to struct statfs(64)

2010-08-09T20:48:44Z

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 Signed-off-by: Al Viro

pass a struct path to vfs_statfs

2010-08-09T20:48:42Z

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 Signed-off-by: Al Viro
