* Btrfs-progs: add support for device replace procedureStefan Behrens2013-01-31
| | | | | | | | | | | This is the user mode part of the device replace patch series. The command group "btrfs replace" is added with three commands: - btrfs replace start srcdev|srcdevid targetdev [-Bfr] mount_point - btrfs replace status mount_point [-1] - btrfs replace cancel mount_point Signed-off-by: Stefan Behrens <sbehrens@giantdisaster.de>
* Btrfs-progs: add command to get/reset device stats via ioctlStefan Behrens2013-01-31
| | | | | | | | "btrfs device stats" is used to retrieve and print the device stats. "btrfs device stats -z" is used to atomically retrieve, reset and print the stats. Signed-off-by: Stefan Behrens <sbehrens@giantdisaster.de>
* Btrfs-progs: make two utility functions globally availableStefan Behrens2013-01-30
| | | | | | | | Two convenient utility functions that have so far been local to scrub are moved to utils.c. They will be used in the device stats code in a following commit. Signed-off-by: Stefan Behrens <sbehrens@giantdisaster.de>
* Btrfs-progs: move open_file_or_dir() to utils.cAnand Jain2013-01-30
| | | | | | | | | | | The definition of the function open_file_or_dir() is moved from common.c to utils.c in order to be able to share some common code between scrub and the device stats in the following step. That common code uses open_file_or_dir(). Since open_file_or_dir() makes use of the function dirfd(3), the required XOPEN version was raised from 6 to 7.

* btrfs-progs: fix unaligned accesses v2Ben Peddell2013-01-28
| | | | | | | | | | | | | | | gcc optimizes out the memcpy calls at -O2 and -Os. Replacing memcpy with memmove does't work - gcc treats memmove the same way it treats memcpy. This patch brings in {get|put}_unaligned_le{16|32|64} (using the packed struct method), and uses them in the failing get/set calls. On architectures where unaligned accesses are cheap, these unaligned macros should be optimized out by the compiler. Signed-off-by: Ben Peddell <klightspeed@killerwolves.net>

* Btrfs-progs: add btrfs device ready commandJosef Bacik2013-01-23
| | | | | | | | | | | This command will be used by things like dracut that wish to know very simply if all of the devices have been added to the kernel cache yet for the device to be fully mounted. This keeps initrd's from constantly having to try to mount the file system until it succeeds every time a device is added to the system.

* Btrfs-progs: detect if the disk we are formatting is a ssdJosef Bacik2013-01-23
| | | | | | | | | | | | | | Patch rebased because of changes in mkfs.c but otherwise the same as created by Josef Bacik SSD's do not gain anything by having metadata DUP turned on. The underlying file system that is a part of all SSD's could easily map duplicate metadat blocks into the same erase block which effectively eliminates the benefit of duplicating the metadata on disk. So detect if we are formatting a single SSD drive and if we are do not use DUP. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com> Signed-off-by: Gene Czarcinski <gene@czarc.net>
* btrfs-progs: Use sysconf instead of getpagesizeEric Sandeen2013-01-23
| | | | | | | | | | | | | | | | | | Rawhide is getting cranky with posix compliance, and a few things have stopped building. getpagesize() is now only available -with- __USE_XOPEN_EXTENDED or __USE_BSD, and NOT __USE_XOPEN2K. _GNU_SOURCE must define __USE_XOPEN2K because getpagesize() has gone away for mkfs. I gave up and used sysconf. Also, something used to pull in stat that no longer does, so things like S_ISREG weren't getting defined. The following fixes things for me.

* btrfs-progs: fix build, manpage compression commandChristian Hesse2013-01-23
| | | | | | | | | | | | | | | man pages for btrfs-progs are compressed by gzip by default. In Makefile the variable GZIP is use, this evaluates to 'gzip gzip' on my system. From man gzip: > The environment variable GZIP can hold a set of default options for gzip. > These options are interpreted first and can be overwritten by explicit > command line parameters.

* Btrfs-progs: bugfix for subvolume parent determination in btrfs sendJan Schmidt2013-01-21
| | | | | | | | | | We missed to add the default subvolume, because it has no ROOT_BACKREF_ITEM. This made get_parent always fail for direct decendants of the default subvolume, resulting in lots of full streams where incremental streams were requested.

* Btrfs-progs: correcting misnamed parameter options for btrfs sendJan Schmidt2013-01-21
| | | | | | | | | | | | Unfortunately, the command line options for btrfs send were misnamed. The -i option should not be used to give "clone sources", we'll be using -c instead. Compatibily note: -i option was broken anyway, which makes it less critical renaming it. For potential users of the old option style, we emit a fatal warning if the -i option is used.

* Btrfs-progs: fix arg parsing for btrfs qgroup limit commandsWang Shilong2013-01-21
| | | | | | | | | | | | | | | | | | | We can use this command in two ways. 1. btrfs qgroup limit size qgroupid path 2. btrfs qgroup limit size path Before applying this patch, we differentiate them by check the parsing result of the second argument. It is not so good because it may make some mistakes, For example: btrfs qgroup limit 1M 123456 ^ It is a subvolume name. In fact, we can differentiate them just by the number of arguments, so fix it by this way.

* Btrfs-progs: bugfix for scrubbing single devicesArne Jansen2013-01-18
| | | | | | | | | | Scrub can be invoked to scrub only a single device of a (mounted) filesystem. The code determines whether the given path is a mountpoint of a filesystem by issueing a btrfs-specific ioctl to it. Only in case of EINVAL it assumed it may be a device, all other errnos just caused it fail, but some devices (correctly) return ENOTTY. This patch adds this to the error check.

| | | | | | | | | | | Let mkfs accept '-a' option and not complain. When a partition has non-zero value in the fs_passno filed in /etc/fstab, the fsck is run but fails and boot stops. As fsck does not break things currently, it's safe to ignore the option and let the boot proceed.

* Btrfs-progs: Fix compiler warnings on PPC64Wade Cline2013-01-17
| | | | | | | | | | | | | | | | The kernel uses unsigned long long for u64, but PPC64 uses unsigned long by default. This results in compilation warnings such as: print-tree.c:333: warning: format '%llu' expects type 'long long unsigned int', but argument 4 has type 'u64' To fix this, the macro __KERNEL__ needs to be defined before including the file <asm/types.h>. This can be done by defining the macro in "kerncompat.h" and making it the first included file in the relevant header files; this fixes the compiler warnings on PPC64.
