If an attempt at contacting a receiver or a device fails because the
receiver or device never responds, don't restart the communication, only
restart it if the receiver or device answers that it's busy, as originally
intended.

This was the behaviour on communication timeout before commit 586e8fed

This fixes some overly long waits in a critical path on boot, when

In commit a44be64b ("ext4: don't clear SB_RDONLY when remounting
r/w until quota is re-enabled") we defer clearing tyhe SB_RDONLY flag
in struct super.  However, we didn't defer when we checked sb_rdonly()
to determine the lazy itable init thread should be enabled, with the
next result that the lazy inode table initialization would not be
properly started.  This can cause generic/231 to fail in ext4's
nojournal mode.

Fix this by moving when we decide to start or stop the lazy itable
init thread to after we clear the SB_RDONLY flag when we are
remounting the file system read/write.

that branch was also used for directories and symlinks and since the

as it should. Fix the problem by adding handling for non-regular files.

For devices not attached to a port multiplier and managed directly by
libata, the device number passed to ata_find_dev() must always be lower
than the maximum number of devices returned by ata_link_max_devices().
That is 1 for SATA devices or 2 for an IDE link with master+slave
devices. This device number is the SCSI device ID which matches these
constraints as the IDs are generated per port and so never exceed the
maximum number of devices for the link being used.

However, for libsas managed devices, SCSI device IDs are assigned per
struct scsi_host, leading to device IDs for SATA devices that can be
well in excess of libata per-link maximum number of devices. This
results in ata_find_dev() to always return NULL for libsas managed
devices except for the first device of the target scsi_host with ID
(device number) equal to 0. This issue is visible by executing the
hdparm utility, which fails. E.g.:

hdparm -i /dev/sdX
/dev/sdX:
  HDIO_GET_IDENTITY failed: No message of desired type

Fix this by rewriting ata_find_dev() to ignore the device number for
non-PMP attached devices with a link with at most 1 device, that is SATA
devices. For these, the device number 0 is always used to
return the correct pointer to the struct ata_device of the port link.
This change excludes IDE master/slave setups (maximum number of devices
per link is 2) and port-multiplier attached devices. Also, to be
consistant with the fact that SCSI device IDs and channel numbers used
as device numbers are both unsigned int, change the devno argument of
ata_find_dev() to unsigned int.

Pull tracing fixes from Steven Rostedt:
 "User events:

   - Use long instead of int for storing the enable set/clear bit, as it
     was found that big endian machines could end up using the wrong
     bits.

   - Split allocating mm and attaching it. This keeps the allocation
     separate from the registration and avoids various races.

   - Remove RCU locking around pin_user_pages_remote() as that can
     schedule. The RCU protection is no longer needed with the above
     split of mm allocation and attaching.

   - Rename the "link" fields of the various structs to something more
     meaningful.

   - Add comments around user_event_mm struct usage and locking
     requirements.

  Timerlat tracer:

   - Fix missed wakeup of timerlat thread caused by the timerlat
     interrupt triggering when tracing is off. The timer interrupt
     handler needs to always wake up the timerlat thread regardless if
     tracing is enabled or not, otherwise, it will never wake up.

  Histograms:

   - Fix regression of breaking the "stacktrace" modifier for variables.
     That modifier cannot be used for values, but can be used for
     variables that are passed from one histogram to the next. This was
     broken when adding the restriction to values as the variable logic
     used the same code.

   - Rename the special field "stacktrace" to "common_stacktrace".

     Special fields (that are not actually part of the event, but can
     act just like event fields, like 'comm' and 'timestamp') should be
     prefixed with 'common_' for consistency. To keep backward
     compatibility, 'stacktrace' can still be used (as with the special
     field 'cpu'), but can be overridden if the event has a field called
     'stacktrace'.

   - Update the synthetic event selftests to use the new name (synthetic
     events are created by histograms)

  Tracing bootup selftests:

   - Reorganize the code to keep artifacts of the selftests not compiled
     in when selftests are not configured.

   - Add various cond_resched() around the selftest code, as the
     softlock watchdog was triggering much more often. It appears that
     the kernel runs slower now with full debugging enabled.

   - While debugging ftrace with ftrace (using an instance ring buffer
     instead of the top level one), I found that the selftests were
     disabling prints to the debug instance.

     This should not happen, as the selftests only disable printing to
     the main buffer as the selftests examine the main buffer to see if
     it has what it expects, and prints can make the tests fail.

     Make the selftests only disable printing to the toplevel buffer,
     and leave the instance buffers alone"

This reverts commit 9828ed3f.

Sadly, it does seem to cause failures to load modules. Johan Hovold reports:

 "This change breaks module loading during boot on the Lenovo Thinkpad
  X13s (aarch64).

  Specifically it results in indefinite probe deferral of the display
  and USB (ethernet) which makes it a pain to debug. Typing in the dark
  to acquire some logs reveals that other modules are missing as well"

Since this was applied late as a "let's try this", I'm reverting it
asap, and we can try to figure out what goes wrong later.  The excessive
parallel module loading problem is annoying, but not noticeable in
normal situations, and this was only meant as an optimistic workaround
for a user-space bug.

One possible solution may be to do the optimistic exclusive open first,
and then use a lock to serialize loading if that fails.

When all kernel debugging is enabled (lockdep, KSAN, etc), the function
graph enabling and disabling can take several seconds to complete. The
function_graph selftest enables and disables function graph tracing
several times. With full debugging enabled, the soft lockup watchdog was
triggering because the selftest was running without ever scheduling.

Add cond_resched() throughout the test to make sure it does not trigger
the soft lockup detector.

The tracing_selftest_running and tracing_selftest_disabled variables were
to keep trace_printk() and other writes from affecting the tracing
selftests, as the tracing selftests would examine the ring buffer to see
if it contained what it expected or not. trace_printk() and friends could
add to the ring buffer and cause the selftests to fail (and then disable
the tracer that was being tested). To keep that from happening, these
variables were added and would keep trace_printk() and friends from
writing to the ring buffer while the tests were going on.

But this was only the top level ring buffer (owned by the global_trace
instance). There is no reason to prevent writing into ring buffers of
other instances via the trace_array_printk() and friends. For the
functions that could be used by other instances, check if the global_trace
is the tracer instance that is being written to before deciding to not
allow the write.

There's no reason to test the condition variables tracing_selftest_running
or tracing_selftest_delete when tracing selftests are not enabled. Make
them define 0s when not the selftests are not configured in.

As there are more and more internal selftests being added to the Linux
kernel (KSAN, lockdep, etc) the selftests are taking longer to run when
these are enabled. Add a cond_resched() to the calling of
do_run_tracer_selftest() to force a schedule if NEED_RESCHED is set,
otherwise the soft lockup watchdog may trigger on boot up.

The variables tracing_selftest_running and tracing_selftest_disabled are
only used for when CONFIG_FTRACE_STARTUP_TEST is enabled. Make them only
visible within the selftest code. The setting of those variables are in
the register_tracer() call, and set in a location where they do not need
to be. Create a wrapper around run_tracer_selftest() called
do_run_tracer_selftest() which sets those variables, and have
register_tracer() call that instead.

Having those variables only set within the CONFIG_FTRACE_STARTUP_TEST
scope gets rid of them (and also the ability to remove testing against
them) when the startup tests are not enabled (most cases).

Add a new flag, EXT4_IGET_EA_INODE which indicates whether the inode
is expected to have the EA_INODE flag or not.  If the flag is not
set/clear as expected, then fail the iget() operation and mark the
file system as corrupted.

This commit also makes the ext4_iget() always perform the
is_bad_inode() check even when the inode is already inode cache.  This
allows us to remove the is_bad_inode() check from the callers of
ext4_iget() in the ea_inode code.
