will get re-allocated, and all old streams' information will
be copied to the new ones and the old ones will be freed.

In xrep_findroot_block, we work out the btree type and correctness of a
given block by calling different btree verifiers on root block
candidates. However, we leave the NULL b_ops while ->verify_read
validates the block, which means that if the verifier calls
xfs_buf_verifier_error it'll crash on the null b_ops. Fix it to set
b_ops before calling the verifier and unsetting it if the verifier
fails.
Furthermore, improve the documentation around xfs_buf_ensure_ops, which
is the function that is responsible for cleaning up the b_ops state of
buffers that go through xrep_findroot_block but don't match anything.

As of commit e339dd8d8b ("xfs: use sync buffer I/O for sync delwri
queue submission"), the delwri submission code uses sync buffer I/O
for sync delwri I/O. Instead of waiting on async I/O to unlock the
buffer, it uses the underlying sync I/O completion mechanism.
If delwri buffer submission fails due to a shutdown scenario, an
error is set on the buffer and buffer completion never occurs. This
can cause xfs_buf_delwri_submit() to deadlock waiting on a
completion event.
We could check the error state before waiting on such buffers, but
that doesn't serialize against the case of an error set via a racing
I/O completion. Instead, invoke I/O completion in the shutdown case
regardless of buffer I/O type.

The cached writeback mapping is EOF trimmed to try and avoid races
between post-eof block management and writeback that result in
sending cached data to a stale location. The cached mapping is
currently trimmed on the validation check, which leaves a race
window between the time the mapping is cached and when it is trimmed
against the current inode size.
For example, if a new mapping is cached by delalloc conversion on a
blocksize == page size fs, we could cycle various locks, perform
memory allocations, etc. in the writeback codepath before the
associated mapping is eventually trimmed to i_size. This leaves
enough time for a post-eof truncate and file append before the
cached mapping is trimmed. The former event essentially invalidates
a range of the cached mapping and the latter bumps the inode size
such the trim on the next writepage event won't trim all of the
invalid blocks. fstest generic/464 reproduces this scenario
occasionally and causes a lost writeback and stale delalloc blocks
warning on inode inactivation.
To work around this problem, trim the cached writeback mapping as
soon as it is cached in addition to on subsequent validation checks.
This is a minor tweak to tighten the race window as much as possible
until a proper invalidation mechanism is available.

When the vblank irq happens, kernel time subsystem executes
`vkms_vblank_simulate`. In parallel or not, it prepares all stuff
necessary to the next vblank with arm, and it must flush these stuff
before the next vblank irq. However, vblank counter is ahead when arm is
executed in parallel with handle vblank.

Then, we should guarantee that the vblank interval time is correct (not

is correct when finish the vblank handle.

kms_flip tests are breaking on vkms when simulate vblank because vblank
event sequence count returns one extra frame after arm vblank event to
make a page flip.
When vblank interrupt happens, userspace processes the vblank event and
issues the next page flip command. Kernel calls queue_work to call
commit_planes and arm the new page flip. The next vblank picks up the
newly armed vblank event and vblank interrupt happens again.
The arm and vblank event are asynchronous, then, on the next vblank, we
receive x+2 from `get_vblank_timestamp`, instead x+1, although timestamp
and vblank seqno matches.
Function `get_vblank_timestamp` is reached by 2 ways:
- from `drm_mode_page_flip_ioctl`: driver is doing one atomic
operation to synchronize planes in the same output. There is no
vblank simulation, the `drm_crtc_arm_vblank_event` function adds 1
on vblank count, and the variable in_vblank_irq is false
- from `vkms_vblank_simulate`: since the driver is doing a vblank
simulation, the variable in_vblank_irq is true.
Fix this problem subtracting one vblank period from vblank_time when
`get_vblank_timestamp` is called from trace `drm_mode_page_flip_ioctl`,
i.e., is not a real vblank interrupt, and getting the timestamp and
vblank seqno when it is a real vblank interrupt.
The reason for all this is that get_vblank_timestamp always supplies the
timestamp for the next vblank event. The hrtimer is the vblank
simulator, and it needs the correct previous value to present the next
vblank. Since this is how hw timestamp registers work and what the
vblank core expects.

net: y2038-safe socket timestamps
The series introduces new socket timestamps that are
y2038 safe.
The time data types used for the existing socket timestamp
options: SO_TIMESTAMP, SO_TIMESTAMPNS and SO_TIMESTAMPING
are not y2038 safe. The series introduces SO_TIMESTAMP_NEW,
SO_TIMESTAMPNS_NEW and SO_TIMESTAMPING_NEW to replace these.
These new timestamps can be used on all architectures.
The alternative considered was to extend the sys_setsockopt()
by using the flags. We did not receive any strong opinions about
either of the approaches. Hence, this was chosen, as glibc folks
preferred this.
The series does not deal with updating the internal kernel socket
calls like rxrpc to make them y2038 safe. This will be dealt
with separately.
Note that the timestamps behavior already does not match the
man page specific behavior:
SIOCGSTAMP
This ioctl should only be used if the socket option SO_TIMESTAMP
is not set on the socket. Otherwise, it returns the timestamp of
the last packet that was received while SO_TIMESTAMP was not set,
or it fails if no such packet has been received,
(i.e., ioctl(2) returns -1 with errno set to ENOENT).
The recommendation is to update the man page to remove the above statement.
The overview of the socket timestamp series is as below:
1. Delete asm specific socket.h when possible.
2. Support SO/SCM_TIMESTAMP* options only in userspace.
3. Rename current SO/SCM_TIMESTAMP* to SO/SCM_TIMESTAMP*_OLD.
3. Alter socket options so that SOCK_RCVTSTAMPNS does
not rely on SOCK_RCVTSTAMP.
4. Introduce y2038 safe types for socket timestamp.
5. Introduce new y2038 safe socket options SO/SCM_TIMESTAMP*_NEW.
6. Intorduce new y2038 safe socket timeout options.
Changes since v4:
* Fixed the typo in calling sock_get_timeout()
Changes since v3:
* Rebased onto net-next and fixups as per review comments
* Merged the socket timeout series
* Integrated Arnd's patch to simplify compat handling of timeout syscalls
Changes since v2:
* Removed extra functions to reduce diff churn as per code review
Changes since v1:
* Dropped the change to disentangle sock flags
* Renamed sock_timeval to __kernel_sock_timeval
* Updated a few comments
* Added documentation changes
====================

SO_RCVTIMEO and SO_SNDTIMEO socket options use struct timeval
as the time format. struct timeval is not y2038 safe.
The subsequent patches in the series add support for new socket
timeout options with _NEW suffix that will use y2038 safe
data structures. Although the existing struct timeval layout
is sufficiently wide to represent timeouts, because of the way
libc will interpret time_t based on user defined flag, these
new flags provide a way of having a structure that is the same
for all architectures consistently.
Rename the existing options with _OLD suffix forms so that the
right option is enabled for userspace applications according
to the architecture and time_t definition of libc.

Subsequent patches in the series add new y2038 safe socket
option to be used in the place of SO_TIMESTAMP_OLD.

format at that time.

This is a cleanup to prepare for the addition of 64-bit time_t
in O_SNDTIMEO/O_RCVTIMEO. The existing compat handler seems
unnecessarily complex and error-prone, moving it all into the
main setsockopt()/getsockopt() implementation requires half
as much code and is easier to extend.
32-bit user space can now use old_timeval32 on both 32-bit

__old_kernel_timeval.
