Sometimes when a test kernel passed fine, but on reboot it crashed,
ktest could get stuck and not proceed. This would be frustrating if you
let a test run overnight to find out the next morning that it was stuck
on the first test.
To fix this, I made reboot check for the REBOOT_SUCCESS_LINE. If the
line was not detected, then it would power cycle the box.
What it didn't cover was if the REBOOT_SUCCESS_LINE wasn't defined or if
a 'good' kernel did not display the line. Instead have it search for the
Linux banner "Linux version". The reboot just needs to get to the start
of the next kernel, it does not need to test if the next kernel makes it
to a boot prompt.
After we find the next kernel has booted, then we just wait for either
the REBOOT_SUCCESS_LINE to appear or the timeout.

Although the patchcheck test checks for warnings in the files that were
changed, this check does not catch warnings that were caused by header
file changes and the warnings appear in C files not touched by the
commit.
Add a new option called WARNINGS_FILE. If this option is set, then the
file it points to is read before bulid, and the file should contain a
list of known warnings. If a warning appears in the build, this file is
checked, and if the warning does not exist in this file, then it fails
the build showing the new warning.
If the WARNINGS_FILE points to a file that does not exist, this will
cause any warning in the build to fail.
A new test is also added called "make_warnings_file". This test will
create do a build and record any warnings it finds into the
WARNINGS_FILE. This test is something that can be run before other tests
to build a warnings file of "known warnings", ie, warnings that were
there before your changes.

Options are allowed to use other options, for example:
LOG_FILE = ${OUTPUT_DIR}/${MACHINE}.log
where the option LOG_FILE used the options OUTPUT_DIR and MACHINE.
But if a test option were to use a default option, it will not get
substituted:
OUTPUT_DIR = ${THIS_DIR}/${MACHINE}
TEST_START
OUTPUT_DIR = ${OUTPUT_DIR}/t1
For the above test, OUTPUT_DIR will stay literally "${OUTPUT_DIR}/t1"
and not be converted to "${THIS_DIR}/${MACHINE}/t1". When the test runs,
it will pass the ${OUTPUT_DIR} to the shell, which would probaly
interpret it as "", and the output directory will end up as "/t1".
Change the code where if a test option has its own option name in
its defined field, and a default option exists, then substitute the
default option in its place.

The patchcheck test looks at what files are modified for each patch it
checks and makes sure that those files do not produce any warnings.
Unfortunately, when it read the diffstat, the newlines were added on the
files and this made compares miss warnings, and commits that should not
have passed, ktest let pass.
Fix this by using the perl command "chomp" that strips off whitespace at
the end of lines.

If the user is doing a build or install bisect, there's no reason to
have them define CONSOLE, as the console does not need to be read. The
console only needs to be read for boot tests.
CONSOLE is not required for normal build or install tests, let's not
require it for bisect tests with BISECT_TYPE of build or install.

Pull btrfs fixes from Chris Mason:
"It turns out that we had two crc bugs when running fsx-linux in a
loop. Many thanks to Josef, Miao Xie, and Dave Sterba for nailing it
all down. Miao also has a new OOM fix in this v2 pull as well.
Ilya fixed a regression Liu Bo found in the balance ioctls for pausing
and resuming a running balance across drives.
Josef's orphan truncate patch fixes an obscure corruption we'd see
during xfstests.
Arne's patches address problems with subvolume quotas. If the user
destroys quota groups incorrectly the FS will refuse to mount.
The rest are smaller fixes and plugs for memory leaks."

btrfs_start_delalloc_inodes() locks the delalloc_inodes list, fetches the
first inode, unlocks the list, triggers btrfs_alloc_delalloc_work/
btrfs_queue_worker for this inode, and then it locks the list, checks the
head of the list again. But because we don't delete the first inode that it
deals with before, it will fetch the same inode. As a result, this function
allocates a huge amount of btrfs_delalloc_work structures, and OOM happens.
Fix this problem by splice this delalloc list.

First, though the current transaction->aborted check can stop the commit early
and avoid unnecessary operations, it is too early, and some transaction handles
don't end, those handles may set transaction->aborted after the check.
Second, when we commit the transaction, we will wake up some worker threads to
flush the space cache and inode cache. Those threads also allocate some transaction
handles and may set transaction->aborted if some serious error happens.
So we need more check for ->aborted when committing the transaction. Fix it.

I noticed a WARN_ON going off when adding csums because we were going over
the amount of csum bytes that should have been allowed for an ordered
extent. This is a leftover from when we used to hold the csums privately
for direct io, but now we use the normal ordered sum stuff so we need to
make sure and check if we've moved on to another extent so that the csums
are added to the right extent. Without this we could end up with csums for
bytenrs that don't have extents to cover them yet. Thanks,

For compressed extents, the range of checksum is covered by disk length,
and the disk length is different with ram length, so we need to use disk
length instead to get us the right checksum.

A user reported a BUG_ON(ret) that occured during tree log replay. Ret was
-EAGAIN, so what I think happened is that we removed an extent that covered
a bitmap entry and an extent entry. We remove the part from the bitmap and
return -EAGAIN and then search for the next piece we want to remove, which
happens to be an entire extent entry, so we just free the sucker and return.
The problem is ret is still set to -EAGAIN so we trip the BUG_ON(). The
user used btrfs-zero-log so I'm not 100% sure this is what happened so I've
added a WARN_ON() to catch the other possibility. Thanks,

We drop the extent map tree lock while we're logging extents, so somebody
could come in and merge another extent into this one and screw up our
logging, or they could even remove us from the list which would keep us from
logging the extent or freeing our ref on it, so we need to make sure to not
clear LOGGING until after the extent is logged, and then we can merge it to
adjacent extents. Thanks,
