The context is zeroed in convert_open_fs after and overwrites the rbtree
initialization, which accidentally is the same (NULL).

It's not really necessary to configure and regenerate Makefiles in cases
like adding a new source file. The build environment and optional
features are not affected by that.

The convert and image utilities used include, but we specify the headers
by path relative to the toplevel directory for clarity. The compiler
option is not needed.

The dependencies are duplicated in many targets, but we can use the $^
variable to simplify the command line.
Signed-off-by: David Sterba <dsterba@suse.com>
Reorder target dependencies:
1) target-specific objects
2) common objects
3) library objects
4) static libraries
1-3 are for faster detection of build failures, the specific objects
reflect changes to the source, but otherwise is only a cosmetic change.
The 4 is for correct order during linking, if we'd use the $^ variable.

Introduce a new macro, BTRFS_SB_OFFSET() to calculate backup superblock
offset, this is handy if one wants to initialize static array at
declaration time.

Large numbers like (1024 * 1024 * 1024) may cost reader/reviewer to
waste one second to convert to 1G.
Introduce kernel include/linux/sizes.h to replace any intermediate
number larger than 4096 (not including 4096) to SZ_*.

btrfs-progs: qgroup: add sync option to 'qgroup show'

The sync call is unlikely to fail so we optimistically turn it to a
warning if that happens so we return inaccurate numbers instead of a
hard exit.

The value of sort option ('S') is not used for option letter.
Therefore, I'll change the single letter to non-character.

The 'qgroup show' command does not synchronize filesystem.
Therefore, 'qgroup show' may not display the correct value unless
synchronized with 'filesystem sync' command etc.
So add the '--sync' option so that we can choose whether or not
to synchronize when executing the command.

The assertion and warn/bug have reversed condition checks, using the
same helpers drops the exact value, so we'll print the message directly
without the helpers.

We want to pass unmodified condition down to the handlers so we can't
use assert_trace for that purpose.
Signed-off-by: David Sterba <dsterba@suse.com>
Due to commit 00e769d04c2c83029d6c71(btrfs-progs: Correct value printed
by assertions/BUG_ON/WARN_ON), which changed the assert_trace()
parameter, the condition passed to assert/WARN_ON/BUG_ON are logical
notted for backtrace enabled and disabled case.
Such behavior makes us easier to pass value wrong, and in fact it did
cause us to pass wrong condition for ASSERT().
Instead of passing different conditions for ASSERT/WARN_ON/BUG_ON()
manually, this patch will use ASSERT() to implement the resting
ASSERT/WARN_ON/BUG() for disable backtrace case, and use assert_trace()
to implement ASSERT() and BUG_ON(), to allow them to print correct
value.
Also, move WARN_ON() out of the ifdef branch, as it's completely the
same for both branches.

If we call "btrfs quota rescan -w", it will attempt to start the rescan
operation, wait for it, and then print the "quota rescan started" message.
The wait could last an arbitrary amount of time, so printing it after
the wait isn't very helpful.
This patch reworks how we print the rescan started message as well as the
printing of the messages, including adding an error message for status
query failures (which could be EPERM/EFAULT/ENOMEM, not just no rescan
in progress) and wait failures.

While performing a memcpy, we are copying from uninitialized dst
as opposed to src->data. Though using eb->len is correct, I used
src->len to make it more readable.
