From d3e3b7eac886fb1383db2f22b81550fa6d87f62f Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 6 Jul 2017 15:50:27 +0100 Subject: afs: Add metadata xattrs Add xattrs to allow the user to get/set metadata in lieu of having pioctl() available. The following xattrs are now available: - "afs.cell" The name of the cell in which the vnode's volume resides. - "afs.fid" The volume ID, vnode ID and vnode uniquifier of the file as three hex numbers separated by colons. - "afs.volume" The name of the volume in which the vnode resides. For example: # getfattr -d -m ".*" /mnt/scratch getfattr: Removing leading '/' from absolute path names # file: mnt/scratch afs.cell="mycell.myorg.org" afs.fid="10000b:1:1" afs.volume="scratch" Signed-off-by: David Howells Signed-off-by: Linus Torvalds --- fs/afs/file.c | 1 + 1 file changed, 1 insertion(+) (limited to 'fs/afs/file.c') diff --git a/fs/afs/file.c b/fs/afs/file.c index 0d5b8508869b..510cba15fa56 100644 --- a/fs/afs/file.c +++ b/fs/afs/file.c @@ -46,6 +46,7 @@ const struct inode_operations afs_file_inode_operations = { .getattr = afs_getattr, .setattr = afs_setattr, .permission = afs_permission, + .listxattr = afs_listxattr, }; const struct address_space_operations afs_fs_aops = { -- cgit v1.2.3
