The BUG_ON() at ocfs2_num_free_extents() handles the error that
l_tree_deepth of leaf extent block just read form disk is invalid. This
error is mostly caused by file system metadata corruption on the disk.
There is no need to call BUG_ON() to handle such errors. We can return
error code, since the caller can deal with errors from
ocfs2_num_free_extents(). Also, we should make the file system read-only
to avoid the damage from expanding.
Therefore, BUG_ON() is removed and ocfs2_error() is called instead.

When the client is required to use TEST_STATEID to discover which
delegation(s) have been revoked, it may continually test delegations at the
head of the list if the server continues to be unsatisfied and send
SEQ4_STATUS_RECALLABLE_STATE_REVOKED. For a large number of delegations
this behavior is prone to live-lock because the client may never be able to
test and free revoked state at the end of the list since the
SEQ4_STATUS_RECALLABLE_STATE_REVOKED will cause us to flag delegations at
the head of the list to be tested. This problem is further exacerbated by
the state manager's willingness to be scheduled out on a busy system while
testing the list of delegations.
Keep a generation counter for each attempt to test all delegations, and
skip delegations that have already been tested in the current pass.

Setting softlockup_panic from do_sysctl_args() causes it to take effect
later in boot. The lockup detector is enabled before SMP is brought
online, but do_sysctl_args runs afterwards. If a user wants to set
softlockup_panic on boot and have it trigger should a softlockup occur
during onlining of the non-boot processors, they could do this prior to
commit f117955a2255 ("kernel/watchdog.c: convert {soft/hard}lockup boot

Gao Xiang has reported that on ext4 O_SYNC direct IO does not properly
sync file size update and thus if we crash at unfortunate moment, the
file can have smaller size although O_SYNC IO has reported successful
completion. The problem happens because update of on-disk inode size is
handled in ext4_dio_write_iter() *after* iomap_dio_rw() (and thus
dio_complete() in particular) has returned and generic_file_sync() gets
called by dio_complete(). Fix the problem by handling on-disk inode size
update directly in our ->end_io completion handler.

syzbot reports that the following warning from ext4_iomap_begin()
triggers as of the commit referenced below:
if (WARN_ON_ONCE(ext4_has_inline_data(inode)))
return -ERANGE;
This occurs during a dio write, which is never expected to encounter
an inode with inline data. To enforce this behavior,
ext4_dio_write_iter() checks the current inline state of the inode
and clears the MAY_INLINE_DATA state flag to either fall back to
buffered writes, or enforce that any other writers in progress on
the inode are not allowed to create inline data.
The problem is that the check for existing inline data and the state
flag can span a lock cycle. For example, if the ilock is originally
locked shared and subsequently upgraded to exclusive, another writer
may have reacquired the lock and created inline data before the dio
write task acquires the lock and proceeds.
The commit referenced below loosens the lock requirements to allow
some forms of unaligned dio writes to occur under shared lock, but
AFAICT the inline data check was technically already racy for any
dio write that would have involved a lock cycle. Regardless, lift
clearing of the state bit to the same lock critical section that
checks for preexisting inline data on the inode to close the race.

Fixes some xfstests including generic/564 and generic/157
The "sfu" mount option can be useful for creating special files (character
and block devices in particular) but could not create FIFOs. It did
recognize existing empty files with the "system" attribute flag as FIFOs
but this is too general, so to support creating FIFOs more safely use a new
tag (but the same length as those for char and block devices ie "IntxLNK"
and "IntxBLK") "LnxFIFO" to indicate that the file should be treated as a
FIFO (when mounted with the "sfu"). For some additional context note that
"sfu" followed the way that "Services for Unix" on Windows handled these
special files (at least for character and block devices and symlinks),
which is different than newer Windows which can handle special files
as reparse points (which isn't an option to many servers).

Pull execve updates from Kees Cook:
- Support non-BSS ELF segments with zero filesz
Eric Biederman and I refactored ELF segment loading to handle the
case where a segment has a smaller filesz than memsz. Traditionally
linkers only did this for .bss and it was always the last segment. As
a result, the kernel only handled this case when it was the last
segment. We've had two recent cases where linkers were trying to use
these kinds of segments for other reasons, and the were in the middle
of the segment list. There was no good reason for the kernel not to
support this, and the refactor actually ends up making things more
readable too.
- Enable namespaced binfmt_misc
Christian Brauner has made it possible to use binfmt_misc with mount
namespaces. This means some traditionally root-only interfaces (for
adding/removing formats) are now more exposed (but believed to be
safe).
- Remove struct tag 'dynamic' from ELF UAPI
Alejandro Colomar noticed that the ELF UAPI has been polluting the
struct namespace with an unused and overly generic tag named
"dynamic" for no discernible reason for many many years. After
double-checking various distro source repositories, it has been
removed.
