* btrfs-progs: convert strerror to implicit %mDavid Sterba2018-10-31
| | | | | | | | | | | | | | | Similar to the changes where strerror(errno) was converted, continue with the remaining cases where the argument was stored in another variable. The savings in object size are about 4500 bytes: $ size btrfs.old btrfs.new text data bss dec hex filename 805055 24248 19748 849051 cf49b btrfs.old 804527 24248 19748 848523 cf28b btrfs.new Signed-off-by: David Sterba <dsterba@suse.com>

* btrfs-progs: autoconf: use standard PACKAGE_* macrosKarel Zak2015-01-28
| | | | | | | | | | | | | - use standard PACKAGE_{NAME,VERSION,STRING,URL,...} autoconf macros rather than homemade BTRFS_BUILD_VERSION - don't #include version.h, now the file is necessary for library API only Note that "btrfs version" returns "btrfs-progs <version>" instead of the original confusing "btrfs <version>".

* btrfs-progs: drop feature defines from C files, in favour of CFLAGS definesDimitri John Ledkov2015-01-27
| | | | | | | | | | | | | | | | | | | | | | glibc 2.10+ (5+ years old) enables all the desired features: _XOPEN_SOURCE 700, __XOPEN2K8, POSIX_C_SOURCE, DEFAULT_SOURCE; with a single _GNU_SOURCE define in the makefile alone. For portability to other libc implementations (e.g. dietlibc) _XOPEN_SOURCE=700 is also defined. This also resolves Debian bug report filed by Michael Tautschnig - "Inconsistent use of _XOPEN_SOURCE results in conflicting declarations". Whilst I was not able to reproduce the results, the reported fact is that _XOPEN_SOURCE set to 500 in one set of files (e.g. cmds-filesystem.c) generates/defines different struct stat from other files (cmds-replace.c). This patch thus cleans up all feature defines, and sets them at a consistent level.

* btrfs-progs: use check_argc_* to check arg number for all toolsGui Hecheng2014-08-22
| | | | | | | | | | | | Since this patch: btrfs-progs: move the check_argc_* functions into utils.c All tools including the independent tools(e.g. btrfs-image, btrfs-convert) can share the convenience of the check_argc_* functions, so this patch adopt the argc check functions globally.

* Btrfs-progs: add a btrfs-select-super command to overwrite the superChris Mason2011-10-25
Btrfs stores multiple copies of the superblock, and for common power-failure crashes where barriers were not in use, one of the super copies is often valid while the first copy is not. This adds a btrfs-select-super -s N /dev/xxx command, which can overwrite all the super blocks with a copy that you have already determined is valid with btrfsck -s Signed-off-by: Chris Mason <chris.mason@oracle.com>
