linux.git/fs/statfs.c, branch v3.1 Linux kernel source tree 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. 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) 2010-08-09T20:48:44+00:00 Christoph Hellwig hch@lst.de 2010-07-07T16:53:25+00:00 365b18189789bfa1acd9939e6312b8a4b4577b28 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 2010-08-09T20:48:42+00:00 Christoph Hellwig hch@lst.de 2010-07-07T16:53:11+00:00 ebabe9a9001af0af56c0c2780ca1576246e7a74b 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.
