* btrfs-progs: remove BTRFS_CRC32_SIZE definitionMisono, Tomohiro2018-03-30
| | | | | | | | | | The kernel code no longer has BTRFS_CRC32_SIZE and only uses btrfs_csum_sizes[]. So, update the progs code as well.

* btrfs-progs: treewide: Replace strerror(errno) with %m.Rosen Penev2018-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As btrfs is specific to Linux, %m can be used instead of strerror(errno) in format strings. This has some size reduction benefits for embedded systems. glibc, musl, and uclibc-ng all support %m as a modifier to printf. A quick glance at the BIONIC libc source indicates that it has support for %m as well. BSDs and Windows do not but I do believe them to be beyond the scope of btrfs-progs.

* btrfs-progs: Add zstd supportNick Terrell2017-09-25
| | | | | | | | | | | | | | | | Adds zstd support to the btrfs program. An optional dependency on libzstd >= 1.0.0 is added. Autoconf accepts `--enable-zstd' or `--disable-zstd' and defaults to detecting if libzstd is present using `pkg-config'. The patch is also available in my fork of btrfs-progs [1], which passes Travis-CI with the new tests. The prebuilt binary is available there. I haven't updated Android.mk.

* btrfs-progs: Remove deprecated leafsize usageQu Wenruo2017-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | Leafsize is deprecated for a long time, and kernel has already updated ctree.h to rename sb->leafsize to sb->__unused_leafsize. This patch will remove normal users of leafsize: 1) Remove leafsize member from btrfs_root structure Now only root->nodesize and root->sectorisze. No longer root->leafsize. 2) Remove @leafsize parameter from btrfs_setup_root() function Since no root->leafsize, no need for @leafsize parameter. The remaining user of leafsize will be: 1) btrfs inspect-internal dump-super Reformat the "leafsize" output to "leafsize (deprecated)" and use le32_to_cpu() to do the cast manually. 2) mkfs We still need to set sb->__unused_leafsize to nodesize. Do the manual cast too. 3) convert Same as mkfs, these two superblock setup should be merged later Signed-off-by: Qu Wenruo <quwenruo@cn.fujitsu.com>

* btrfs-progs: dump-super: changes in options to specify superblocksDavid Sterba2016-09-21
| | | | | | | | | | | | Some tools (check, select-super, dump-super) can use the alternate superblocks, but the options are not consistent. To make it less confusing, change the meaning of option -s in 'dump-super' to specify the superblock copy, instead of taking the offset. Though this is a change in UI, the old usage is detected and the result would be the same, no breakage in existing scripts. Signed-off-by: David Sterba <dsterba@suse.com>
