Make some preparatory cleanups prior to running a script to organise the
function declarations within the fs/smb/client/ headers. These include:
(1) Remove "inline" from the dummy cifs_proc_init/clean() functions as
they are in a .c file.
(2) Move should_compress()'s kdoc comment to the .c file and remove kdoc
markers from the comments.
(3) Rename CIFS_ALLOW_INSECURE_LEGACY in #endif comments to have CONFIG_
on the front to allow the script to recognise it.
(4) Don't let comments have bare words at the left margin as that confused
the simplistic function detection code in the script.
(5) Adjust some argument lists so that when and if the cleanup script is
run they don't end up over 100 chars.
(6) Fix a few comments to have missing '*' added or the "*/" moved to
their own lines so that checkpatch doesn't moan over the cleanup
script patch.
(7) Move struct cifs_calc_sig_ctx to cifsglob.h.
(8) Remove some __KERNEL__ conditionals.

Add a tracepoint to log EIO errors and give it the capacity to convey up to
two integers of information. This is then wrapped with three functions:
int smb_EIO(enum smb_eio_trace trace)
int smb_EIO1(enum smb_eio_trace trace, unsigned long info)
int smb_EIO2(enum smb_eio_trace trace, unsigned long info,
unsigned long info2)
depending on how many bits of info are desired to be logged with any
particular trace. The functions all return -EIO and can be used in place
of -EIO.
The trace argument is an enum value that gets translated to a string when
the trace is printed.
This makes is easier to log EIO instances when the client is under high
load than turning on a printk wrapper such as cifs_dbg(). Granted, EIO
could have its own separate EIO printing since EIO shouldn't happen.

STATUS_PRIVILEGE_NOT_HELD indicates that user does not have privilege to
issue some operation, for example to create symlink.
Currently STATUS_PRIVILEGE_NOT_HELD is translated to -EIO. Change it to
-EPERM which better describe this error code.
Note that there is no ERR* code usable in ntstatus_to_dos_map[] table which
can be used to -EPERM translation, so do explicit translation in
map_smb_to_linux_error() function.

NT Status code is 32-bit number, so for comparing two NT Status codes is
needed to check all 32 bits, and not just low 24 bits.
Before this change kernel printed message:
"Status code returned 0x8000002d NT_STATUS_NOT_COMMITTED"
It was incorrect as because NT_STATUS_NOT_COMMITTED is defined as
0xC000002d and 0x8000002d has defined name NT_STATUS_STOPPED_ON_SYMLINK.
With this change kernel prints message:
"Status code returned 0x8000002d NT_STATUS_STOPPED_ON_SYMLINK"
