* btrfs-progs: Fix btrfs fi show by uuid and labelJustin Maggard2014-12-29
| | | | | | | | | | | | | | | | Commit 8be2fff (btrfs-progs: apply realpath for btrfs fi show when mount point is given) changed the behavior of btrfs fi show to return an error if the call to realpath() failed. This broke the ability to specify a filesystem by uuid or label. So let's not consider a failed call to realpath() as an error. If the user really specified a bad device, just return nothing like we did before.

* btrfs-progs: Fix a bug in reset_nlink() which may deletes the recovered fileQu Wenruo2014-12-29
| | | | | | | | | | | | | | | | In reset_nlink(), we believe rec->found_link as accurate number of the valid links. However it only records the number of found DIR_ITEM, so we can't use it as reliable value. Before this patch, in some case, leaf corruption recovery will believe there is a valid backref but don't add_link() since it can't find any valid one and don't put it into the lost+found dir. So the recovered inode will be considered as an orphan item without orphan item and repair_inode_orphan_item() will add orphan item for it, causing all the filename/filetype we recovered being a waste of time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When "/" is Btrfs, "btrfs property <subcommand> /" regards it as non-root by mistake. check_is_root() regards @object as a file system root if the following two conditions are satisfied. a) Both @object and its parent directory are Btrfs object (file system root, subvolume, inode, and device used for Btrfs). b) fsid of the above mentioned two objects are different. It doesn't work if @object is "/" because, in this case, fsid of "/" and its parent (it's also "/"), are the same. * Test environment Two Btrfs file system (not subvolume) "/" and "/home/sat/mnt". * How to reproduce Submit "btrfs prop get" against the above mentioned file systems. * Test Result ** Actual result (without my patch) ========================== ro=false label= # label is displayed because it's a file system root ro=false # label is not displayed even if it's a file system root ========================== ** Expected result (with my patch) ========================== ro=false label= ro=false label=foo # label is displayed =========================== Signed-off-by: Satoru Takeuchi <takeuchi_satoru@jp.fujitsu.com> Reported-by: Naohiro Aota <naota@elisp.net> Reviewed-by: Gui Hecheng <guihc.fnst@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.cz>
