There's a report that a read-only subvolume with a received_uuid set
emits the warning in command 'btrfs subvolume show', which is obviously
wrong.
The reason is that there are different types of root item flags,
depending on how we read them. The check in cmd_subvol_show uses the
ioctl GET_SUBVOL_INFO and the appropriate flag is raw
BTRFS_ROOT_SUBVOL_RDONLY (0x1), while there's another SUBVOL_GETFLAGS that
maps the flags and the raw value is different (BTRFS_SUBVOL_RDONLY, 0x2).
Due to this the warning was issued. Fix that by using the right flag
constant. The test has been extended to check for all combinations of
read-write and received_uuid.

Such search is done by using current filesystem generation as a search

For the incoming extra page size support for subpage (sectorsize <
PAGE_SIZE) cases, the support for metadata will be a critical point.
Currently for subpage support, we require 64K page size, so that no
matter whatever the nodesize is, it will be contained inside one page.
And we will reject any tree block which crosses page boundary.
But for other page size, especially 16K page size, we must support
nodesize differently.
For nodesize < PAGE_SIZE, we will have the same requirement (tree blocks
can't cross page boundary).
While for nodesize >= PAGE_SIZE, we will require the tree blocks to be
page aligned.
To support such feature, we will make btrfs-check to reports more
subpage related warnings for metadata.
This patch will report any tree block which is not nodesize aligned as a
warning.
Existing mkfs/convert has already make sure all new tree blocks are

The current mount detection code in btrfs receive is not quite perfect.
For example, suppose /tmp is mounted as a tmpfs. In that case,

if /tmp2 is just a directory in / mounted as btrfs.

extra reference to the eb (root->commit_root) is leaked, which mkfs

[PROBLEM]
We want to inject $INSTRUMENT (mostly valgrind) before btrfs command but
after root_helper.
Currently we won't inject $INSTRUMENT at all if we are using
root_helper.
This means the coverage is not good enough.
[FIX]
This patch introduce a new function, expand_command(), to handle all
parameter/argument injection, including existing 'btrfs check' inject.
This function will:
- Detect where to inject $INSTRUMENT
If we have root_helper and the command is target command
(btrfs/mkfs.btrfs/btrfs-convert), then we inject $INSTRUMENT after
root_helper.
If we don't have root_helper, and the command is target command,
we inject $INSTRUMENT before the command.
Or we don't inject $INSTRUMENT (it's not the target command).
- Use existing spec facility to inject extra arguments
- Use an array to restore to result
To avoid bash interpret the IFS inside path/commands.
Now we can make sure no matter if we use root_helper, $INSTRUMENT is
always injected corrected.

- misc/004
Filter the output of "btrfs ins min-dev-size"
- misc/009
- misc/013
- misc/024
They are all calling "btrfs ins rootid", so introduce get_subvolid()
function to grab the subvolid properly.
- misc/031

test failed for case 013-extent-tree-rebuild
[CAUSE]
Just as stated by valgrind itself, it can't handle program with
setuid/setgid/setcap.
Thankfully in our case it's mount and we don't really care about it at
all.
[FIX]
Although we could use complex skip pattern to skip mount in valgrind, we
don't really want to run valgrind on mount or sudo command anyway.
So here we do extra check if we're running mount command. And if that's
the case, just skip $INSTRUMENT command.

As seem in issue #192, this test can fail from time to time. The
issue happens when a mount is issued before the new device is processed
by systemd-udevd, as we can see by the og bellow:
[ 2346.028809] BTRFS: device fsid 593e23af-a7e6-4360-b16a-229f415de697 devid 1 transid 6 /dev/loop10 scanned by systemd-udevd (3418)

A few moments after the test failed systemd-udevd processed the new
device (registered the new device under btrfs). This can be tested by
executing a mount after the test failed, resulting in a successful
mount:
$ mount /dev/loop10 /mnt
[ 2398.955254] BTRFS info (device loop10): found metadata UUID change in progress flag, clearing
[ 2398.959416] BTRFS info (device loop10): disk space caching is enabled

This problem can be avoided is we execute "udevadm settle" before the
mount is executed.

The manual page of btrfsck clearly states 'btrfs check --repair' is a

Although this warning is in place users do not read the manual page

Similar to 'btrfs balance' without any filters, add a warning and a
countdown, so users can bail out before eventual corrupting the
filesystem more than it already is.

Add new test image for imode repair in subvolume trees.
The new test cases including the following cases:
- Regular file with bad imode
It still has the valid INODE_REF and parent dir has correct DIR_INDEX
and DIR_ITEM.
In this case, no matter if the file is empty or not, it should be
repaired using the info from DIR_INDEX of parent dir.
- Non-empty regular file with bad imode, and without INODE_REF
The file should be mostly an orphan, so no INODE_REF for imode lookup.
But it has EXTENT_DATA which should be enough for imode repair.
The repair also involves moving the orphan to lost+found dir.
- Non-empty dir with bad imode, and without INODE_REF
Pretty much the same case, but now a directory.
The repair also involves moving the orphan to lost+found dir.
Also rename the existing test case 039-bad-free-space-cache-inode-mode

Fix this by using a new device for restore.
And also, the btrfs-image dump and restore doesn't restore the file
data, so any read on the files should be avoided. So instead of file
data use file stat data for the checksum.

Notes on test:
- Don't use grep -q, as it causes a SIGPIPE during the countdown, and
the balance thus doesn't start.
- The "balance cancel" is superfluous as the last command, but it
