As tasks always wait and kill their io-wq on exec/exit, files are of no
more concern to us, so we don't need to specifically cancel them by hand
in those cases. Moreover we should not, because io_match_task() looks at
req->task->files now, which is always true and so leads to extra
cancellations, that wasn't a case before per-task io-wq.

This is racy - move the blocking into when the task is created and

We go through various hoops to disallow signals for the IO threads, but
there's really no reason why we cannot just allow them. The IO threads
never return to userspace like a normal thread, and hence don't go through
normal signal processing. Instead, just check for a pending signal as part
of the work loop, and call get_signal() to handle it for us if anything
is pending.

With that, we can support receiving signals, including special ones like
SIGSTOP.

check on max supported number of partitionsr, and allows partition with

There were two problems (one of which could cause data corruption)
that were noticed with duplicate extents (ie reflink)
when debugging why various xfstests were being incorrectly skipped
(e.g. generic/138, generic/140, generic/142). First, we were not
updating the file size locally in the cache when extending a
file due to reflink (it would refresh after actimeo expires)
but xfstest was checking the size immediately which was still
0 so caused the test to be skipped.  Second, we were setting
the target file size (which could shrink the file) in all cases
to the end of the reflinked range rather than only setting the
target file size when reflink would extend the file.

Make SMB2 not print out an error when an oplock break is received for an

these unknown handles may also be misleading, so fix that too.

Under SMB1 + POSIX, if an inode is reused on a server after we have read and
cached a part of a file, when we then open the new file with the
re-cycled inode there is a chance that we may serve the old data out of cache
to the application.
This only happens for SMB1 (deprecated) and when posix are used.
The simplest solution to avoid this race is to force a revalidate
on smb1-posix open.

distro, both skip the test case with the log:

  # ./perf test -v 76
  76: daemon operations                                               :
  --- start ---
  test child forked, pid 11687
  test daemon list
  trap: SIGINT: bad trap
  ./tests/shell/daemon.sh: 173: local: cpu-clock: bad variable name
  test child finished with -2
  ---- end ----
  daemon operations: Skip

So the error happens for the variable expansion when use local variable
in the shell script.  Since Debian Buster uses dash but not bash as
non-interactive shell, when execute the daemon testing, it hits a known
issue for dash which was reported [1].

To resolve this issue, one option is to add double quotes for all local
variables assignment, so need to change the code from:

  local line=`perf daemon --config ${config} -x: | head -2 | tail -1`

  ... to:

  local line="`perf daemon --config ${config} -x: | head -2 | tail -1`"

But the testing script has bunch of local variables, this leads to big
changes for whole script.

On the other hand, the testing script asks to use the "local" feature
which is bash-specific, so this patch explicitly uses "#!/bin/bash" to
ensure running the script with bash.

After:

  # ./perf test -v 76
  76: daemon operations                                               :
  --- start ---
  test child forked, pid 11329
  test daemon list
  test daemon reconfig
  test daemon stop
  test daemon signal
  signal 12 sent to session 'test [11596]'
  signal 12 sent to session 'test [11596]'
  test daemon ping
  test daemon lock
  test child finished with 0
  ---- end ----
  daemon operations: Ok
