* btrfs-progs: Make btrfs_header_chunk_tree_uuid() return unsigned longRoss Kirk2014-01-31
| | | | | | | | | | | | Internally, btrfs_header_chunk_tree_uuid() calculates an unsigned long, but casts it to a pointer, while all callers cast it to unsigned long again.

* Btrfs-progs: pass flag to control whether run ioctl in btrfs_scan_for_fsid()Wang Shilong2013-10-16
| | | | | | | | | If some fatal superblocks are damaged, running ioctl will return failure, in this case, we should avoid run ioctl. Signed-off-by: Wang Shilong <wangsl.fnst@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Chris Mason <chris.mason@fusionio.com>

* Btrfs-progs: fix wrong arg sb_bytenr for btrfs_scan_fs_devices()Wang Shilong2013-08-09
| | | | | | | | | | | | | | | | | | | | | For most time, In open_ctree_*(), we use the first superblock (BTRFS_SUPER_INFO_OFFSET). However, for btrfs-convert, we don't, we should pass the correct sb_bytenr to btrfs_scan_fs_devices() rather than always use BTRFS_SUPER_INFO_OFFSET.This patch fix the following regression: mkfs.ext2 <dev> btrfs-convert <dev> warning, device 1 is missing Check tree block failed, want=2670592, have=0 read block failed check_tree_block Couldn't read chunk root Segmentation fault (core dumped) Signed-off-by: Wang Shilong <wangsl.fnst@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Chris Mason <chris.mason@fusionio.com>
* btrfs-progs: Cleanup for using BTRFS_SETGET_STACK instead of raw convertQu Wenruo2013-08-09
| | | | | | | | | | | | Some codes still use the cpu_to_lexx instead of the BTRFS_SETGET_STACK_FUNCS declared in ctree.h. Also added some BTRFS_SETGET_STACK_FUNCS for btrfs_header and btrfs_super.

* Btrfs-progs: Don't free the devices when close the ctreeMiao Xie2013-07-03
| | | | | | | | | | | Some commands(such as btrfs-convert) access the devices again after we close the ctree, so it is better that we don't free the devices objects when the ctree is closed, or we need re-allocate the memory for the devices. We needn't worry the memory leak problem, because all the memory will be freed after the taskes die.

* Btrfs-progs: don't close the file descriptor 0 when closing a deviceMiao Xie2013-07-03
| | | | | | | | | | As we know, the file descriptor 0 is a special number, so we shouldn't use it to initialize the file descriptor of the devices, or we might close this special file descriptor by mistake when we close the devices. "-1" is a better choice. Signed-off-by: Miao Xie <miaox@cn.fujitsu.com> Signed-off-by: Chris Mason <chris.mason@fusionio.com>
* 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>
