This patch resolves the below scenario.
== Process 1 == == Process 2 ==
open(w) open(rw)
begin
write(new_#1)
process_crash
f_op->flush
locks_remove_posix
f_op>release
read (new_#1)
In order to avoid corrupted database caused by new_#1, we must do roll-back
at process_crash time. In order to check that, this patch keeps task which
triggers transaction begin, and does roll-back in f_op->flush before removing
file locks.

When changing a file's acl mask, __f2fs_set_acl() will first set the
group bits of i_mode to the value of the mask, and only then set the
actual extended attribute representing the new acl.
If the second part fails (due to lack of space, for example) and the
file had no acl attribute to begin with, the system will from now on
assume that the mask permission bits are actual group permission bits,
potentially granting access to the wrong users.
Prevent this by only changing the inode mode after the acl has been set.

Use f2fs_dentry_ptr structure to indicate inline dentry structure as
much as possible, so we can wrap inline dentry with size-fixed fields
to the one with size-changeable fields. With this change, we can
handle size-changeable inline dentry more easily.

This adds a perl script to actually parse the MAINTAINERS file, clean up
some whitespace in it, warn about errors in it, and then properly sort
the end result.
My perl-fu is atrocious, so the script has basically been created by
randomly putting various characters in a pile, mixing them around, and
then looking it the end result does anything interesting when used as a
perl script.

Prepping for scripting the MAINTAINERS file cleanup (and possible split)
showed a couple of cases where the headers for a couple of entries were
bogus.
There's a few different kinds of bogosities:
- the X-GENE SOC EDAC case was confused and split over two lines
- there were four entries for "GREYBUS PROTOCOLS DRIVERS" that were all
different things.
- the NOKIA N900 CAMERA SUPPORT" was duplicated
all of which were more obvious when you started doing associative arrays
in perl to track these things by the header (so that we can alphabetize
this thing properly, and so that we might split it up by the data too).

xen/balloon: don't online new memory initially
xen/x86: fix cpu hotplug
xen/grant-table: log the lack of grants
xen/x86: Don't BUG on CPU0 offlining
When setting up the Xenstore watch for the memory target size the new
watch will fire at once. Don't try to reach the configured target size
by onlining new memory in this case, as the current memory size will
be smaller in almost all cases due to e.g. BIOS reserved pages.
Onlining new memory will lead to more problems e.g. undesired conflicts
with NVMe devices meant to be operated as block devices.
Instead remember the difference between target size and current size
when the watch fires for the first time and apply it to any further
size changes, too.
In order to avoid races between balloon.c and xen-balloon.c init calls
do the xen-balloon.c initialization from balloon.c.

When mapping a directory, we want the MAY_WRITE permissions to reflect
whether or not we have permission to modify, add and delete the directory
entries. MAY_EXEC must map to lookup permissions.
On the other hand, for files, we want MAY_WRITE to reflect a permission
to modify and extend the file.
