[PATCH 04/18] xstat: AFS: Return extended attributes [ver #6]
Return extended attributes from the AFS filesystem. This includes the following: (1) The vnode uniquifier as st_gen. (2) The data version number as st_data_version. (3) FS_AUTOMOUNT_FL on mountpoint directories. Signed-off-by: David Howells <dhowells(a)redhat.com> --- fs/afs/inode.c | 13 ++++++++-... 14 Jul 2010 23:05

[PATCH 14/18] xstat: NFS: Use d_automount() rather than abusing follow_link() [ver #6]

[PATCH 18/18] xstat: Provide a mechanism to gather extra results for [f]xstat() [ver #6]
Provide a mechanism in the kernel by which extra results beyond those allocated space in the xstat struct can be returned to userspace. [I'm not sure this is the best way to do this; it's a bit unwieldy. However, I'd rather not overburden struct kstat with fields for every extra result we might want to return ... 14 Jul 2010 23:05

[PATCH 15/18] xstat: CIFS: Use d_automount() rather than abusing follow_link() [ver #6]
Make CIFS use the new d_automount() dentry operation rather than abusing follow_link() on directories. [NOTE: THIS IS UNTESTED!] [Question: Why does cifs_dfs_do_refmount() when the caller has already done that and could pass the result through?] Signed-off-by: David Howells <dhowells(a)redhat.com> Cc: S... 14 Jul 2010 23:05

[PATCH 00/18] Extended file stat functions [ver #6]
Implement a pair of new system calls to provide extended and further extensible stat functions. The second of the associated patches is the main patch that provides these new system calls: ssize_t ret = xstat(int dfd, const char *filename, unsigned atflag, struct xstat_parameters *param... 14 Jul 2010 23:05

[PATCH 12/18] xstat: Add a dentry op to handle automounting rather than abusing follow_link() [ver #6]
Add a dentry op (d_automount) to handle automounting directories rather than abusing the follow_link() inode operation. The operation is keyed off a new inode flag (S_AUTOMOUNT). This makes it easier to add an AT_ flag to suppress terminal segment automount during pathwalk. It should also remove the need for th... 14 Jul 2010 23:05

[PATCH 08/18] xstat: CIFS: Return extended attributes [ver #6]
Return extended attributes from the CIFS filesystem. This includes the following: (1) Return the file creation time as btime. We assume that the creation time won't change over the life of the inode. (2) FS_AUTOMOUNT_FL on referral/submount directories. (3) Deasserting XSTAT_REQUEST_INO in st_resul... 14 Jul 2010 23:05

[PATCH 17/18] xstat: Add an AT_NO_AUTOMOUNT flag to suppress terminal automount [ver #6]
Add an AT_NO_AUTOMOUNT flag to suppress terminal automounting of directories with follow_link semantics. This can be used by fstatat()/xstat() users to permit the gathering of attributes on an automount point and also prevent mass-automounting of a directory of automount points by ls.

[PATCH 03/18] AFS: Use i_generation not i_version for the vnode uniquifier [ver #6]
Store the AFS vnode uniquifier in the i_generation field, not the i_version field of the inode struct. i_version can then be given the AFS data version number.
