To check is btrfs-convert create bad filesystem with

It is happened in progs version <=v4.1.2, and fixed by patch titled:
btrfs: convert: Avoid allocating metadata extent crossing stripe boundary
which was merged in v4.2.
Notice thar this testcase can not report error in old version of
btrfs-progs, because "btrfs check" can't check this type of error

check is "btrfs check" support this check.
So, the above 2 testcase together can check leaf-crossing-stripes

Reason:
When scrub multi-device simultaneously, if some device canceled,
and some device is still running, cancel state have higher priority to
be outputed in global report.
So we can see "scrub aborted" in status line, with running-time keeps
increased.
Fix:
We can increase running state's priority in output, if there is
some device in scrub state, we output running state instead of
cancelled state.

# btrfs-image -r -t0 /tmp/btrfs_image.img /dev/sda6
(hang)
Reason:
The program need to create at least 1 thread for
compression/decompression. If the user specifies -t0, it overwrites the
default value of 1, then the program really creates 0 thread, and
ends up looping
Fix:
We can add a check, to make the program not to allow -t0 argument,
but there is another problem:
For example, on a node with 4 cpus:
btrfs-image -c9 -t1: 4 threads (1 means use NR_CPUS)
-c9 -t2: 2 threads
-c9 -t3: 3 threads
...
(-t1 has more threads than -t2 and -t3)
So we change to use value of 0 as "use NR_CPUS threads", then:
btrfs-image [no -t arg]: use NR_CPUS threads
-t0: use NR_CPUS threads
-t val: use val threads.

btrfs subvolume delete /mnt/btrfs/mysubvol_snap

btrfs subvolume sync /mnt/btrfs

Reason:
List of "deleted subvolumes" are not currectly set.
It caused by a typo of value assign, in detail:
*ids[idx] = sh->offset;
should be:
(*ids)[idx] = sh->offset;
So only first element is set to right memory address.

In btrfs-convert main(), strdup() allocates memory to fslabel but that
memory is not freed. We could fix it by adding free() calls to every

several return paths.
So I fix it by changing the code using strdup() with local array and
strncpy().
And btrfs-convert main() guarantees that string length of fslabel is not
to exceed 'BTRFS_LABEL_SIZE', so it's enough to use strcpy() instead of

btrfs-progs: Add further checks to btrfs replace start command
Add further checks to btrfs replace start command.
The following tests where added in user space before calling
the ioctl():
1) check if the new disk is greather or equal to the old one
2) check if the source device is or a block device or a
numerical dev-id
These checks are already performed in kernel space; however
when "btrfs replace start" is ran in background is not possible
to show any error returned by the ioctl(), so in case of fail
the user had to check dmesg to understand the what happened.

We need not check path before btrfs_free_path() is called because
path is checked in btrfs_free_path().

btrfs-progs: fsck: fix a infinite loop on discount file extent repair
For a special case, discount file extent repair function will cause
infinite loop.
The case is, if the file loses all its extents, we won't have a hole
to fill, causing repair function doing nothing. Since the
I_ERR_DISCOUNT doesn't disappear, fsck will do an infinite loop.
For such case, just puch hole to fill the whole range to fix it.

kerncompat.h assumed that if __GLIBC__ was not defined,

Previous patch detecs inconsistency and unconditionally triggers quota
