* Btrfs-progs: debug-tree, add option to dump a single treeFilipe David Borba Manana2014-08-22
| | | | | | | | | | | | | | | | Very often while debugging filesystems with many subvolumes and/or snapshots, specially when they are large, I want to see only the content of one of the trees. So this change just adds an option to btrfs-debug-tree to allow to specify the id of the tree we're interesting in dumping to stdout. Example: btrfs-debug-tree -t 257 /dev/sdc Will only dump the tree of the first snapshot or subvolume that was created.

* btrfs-progs: prevent close_root if the root to close is potentially NULLGui Hecheng2014-05-02
| | | | | | | | | | Originally only if 'block_only' is specified, the 'fs_root == NULL' will be checked. But if 'block_only' is not specified and close_root will be called blindly without checking 'fs_root == NULL', which is unsafe.

* btrfs-progs: define BTRFS_UUID_UNPARSE_SIZE for uuid unparse buf sizeAnand Jain2014-01-31
| | | | | | | | | we use 37 as the allocation size to hold the uuid_unparse, here it defines BTRFS_UUID_UNPARSE_SIZE for the same. Signed-off-by: Anand Jain <anand.jain@oracle.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Chris Mason <clm@fb.com>
* Btrfs-progs: rework open_ctree to take flags, add a new one V2Josef Bacik2013-11-07
| | | | | | | | | | | So I needed to add a flag to not try to read block groups when doing --init-extent-tree since we could hang there, but that meant adding a whole other 0/1 type flag to open_ctree_fs_info. So instead I've converted it all over to using a flags setting and added the flag that I needed. This has been tested with xfstests and make test.

* Btrfs-progs: add -b to btrfsck to look at backup rootsJosef Bacik2013-11-07
| | | | | | | | | | In some cases the tree root is so hosed we can't get anything useful out of it. So add the -b option to btrfsck to make us look for the most recent backup tree root to use for repair. Then we can hopefully get ourselves into a working state.

* btrfs-progs: drop unused parameter from btrfs_release_pathEric Sandeen2013-09-03
| | | | | | | | | | | | | | | Port of commit b3b4aa7 to userspace. parameter tree root it's not used since commit 5f39d397dfbe140a14edecd4e73c34ce23c4f9ee ("Btrfs: Create extent_buffer interface for large blocksizes") This gets userspace a tad closer to kernelspace by removing this unused parameter that was all over the codebase...

* btrfs-progs: standardize tool source filenamesEric Sandeen2013-04-24
For any btrfs-$FOO executable, rename the main source file from $FOO.c to to btrfs-$FOO.c This makes it slightly more obvious what's building what, and allows us to write a default rule in the Makefile for these tools. (also add btrfs-calc-size to the list of objects to remove on make clean) Signed-off-by: Eric Sandeen <sandeen@redhat.com>
