FreeXid() along with freeing Xid does add a cifsFYI debug message that
prints rc (return code) as well. In some code paths where we set/return
error code after calling FreeXid(), incorrect error code is being
printed when cifsFYI is enabled.
This could be misleading in few cases. For eg.
In cifs_open() if cifs_fill_filedata() returns a valid pointer to
cifsFileInfo, FreeXid() prints rc=-13 whereas 0 is actually being
returned. Fix this by setting rc before calling FreeXid().
Basically convert
FreeXid(xid); rc = -ERR;
return -ERR; => FreeXid(xid);
return rc;
[Note that Christoph would like to replace the GetXid/FreeXid
calls, which are primarily used for debugging. This seems
like a good longer term goal, but although there is an
alternative tracing facility, there are no examples yet
available that I know of that we can use (yet) to
convert this cifs function entry/exit logging, and for
creating an identifier that we can use to correlate
all dmesg log entries for a particular vfs operation
(ie identify all log entries for a particular vfs
request to cifs: e.g. a particular close or read or write
or byte range lock call ... and just using the thread id
is harder). Eventually when a replacement
for this is available (e.g. when NFS switches over and various
samples to look at in other file systems) we can remove the
GetXid/FreeXid macro but in the meantime multiple people
use this run time configurable logging all the time
for debugging, and Suresh's patch fixes a problem
which made it harder to notice some low
memory problems in the log so it is worthwhile
to fix this problem until a better logging
approach is able to be used]

This commit 335f8514f2 has stopped
properly checking if there is any usb serial associated with the tty in
the close function. It happens the close function is called by releasing
the terminal right after opening the device fails.
As an example, open fails with a non-existing device, when probe has
never been called, because the device has never been plugged. This is
common in systems with static modules and no udev.

Update the link script for ARM to use PAGE_SIZE instead of hard-

for the RO_DATA(PAGE_SIZE) macro. As a consequence the PAGE_SIZE
was changed from (1UL << PAGE_SHIFT) to (_AC(1,UL) << PAGE_SHIFT)
because the linker does not understand the "UL" suffix to numeric

This reverts commit ae0e8e8220.
This change had two problems:
1) Since it frees the stats in the drivers' close method, we
can OOPS in the transmit routine.
2) stats are no longer remembered across ifdown/ifup which
disagrees with how every other device operates.
Thanks to analysis and test patch from Serge E. Hallyn

Looking backward for the first space from the end of a line in
/proc/pid/maps does not find the start of the pathname of the mapped
file if it contains a space.
Since the only slashes we have in this file occur in the (absolute!)
pathname column of file mappings, looking for the first slash in a

In hunting down the cause for the hwlat_detector ring buffer spew in
my failed -next builds it became obvious that folks are now treating
ring_buffer as something that is generic independent of tracing and thus,
suitable for public driver consumption.
Given that there are only a few minor areas in ring_buffer that have any
reliance on CONFIG_TRACING or CONFIG_FUNCTION_TRACER, provide stubs for
those and make it generally available.
