      cifs: demote cERROR in build_path_from_dentry to cFYI · fa71f447
      由 Jeff Layton 提交于 
      Running the cthon tests on a recent kernel caused this message to pop
occasionally:

    CIFS VFS: did not end path lookup where expected namelen is 0

Some added debugging showed that namelen and dfsplen were both 0 when
this occurred. That means that the read_seqretry returned true.

Assuming that the comment inside the if statement is true, this should
be harmless and just means that we raced with a rename. If that is the
case, then there's no need for alarm and we can demote this to cFYI.

While we're at it, print the dfsplen too so that we can see what
happened here if the message pops during debugging.

      cifs: Do not set cifs/ntfs acl using a file handle (try #4) · e22906c5
      由 Shirish Pargaonkar 提交于 
      Set security descriptor using path name instead of a file handle.
We can't be sure that the file handle has adequate permission to
set a security descriptor (to modify DACL).

Function set_cifs_acl_by_fid() has been removed since we can't be
sure how a file was opened for writing, a valid request can fail
if the file was not opened with two above mentioned permissions.
We could have opted to add on WRITE_DAC and WRITE_OWNER permissions
to file opens and then use that file handle but adding addtional
permissions such as WRITE_DAC and WRITE_OWNER could cause an
any open to fail.

And it was incorrect to look for read file handle to set a
security descriptor anyway.

      [CIFS] Cleanup use of CONFIG_CIFS_STATS2 ifdef to make transport routines more readable · 789e6661
      由 Steve French 提交于 
      Christoph had requested that the stats related code (in
CONFIG_CIFS_STATS2) be moved into helpers to make code flow more
readable.   This patch should help.   For example the following
section from transport.c

                       spin_unlock(&GlobalMid_Lock);
                       atomic_inc(&ses->server->num_waiters);
                       wait_event(ses->server->request_q,
                                  atomic_read(&ses->server->inFlight)
                                    < cifs_max_pending);
                       atomic_dec(&ses->server->num_waiters);
                       spin_lock(&GlobalMid_Lock);

becomes simpler (with the patch below):
                       spin_unlock(&GlobalMid_Lock);
                       cifs_num_waiters_inc(server);
                       wait_event(server->request_q,
                                  atomic_read(&server->inFlight)
                                    < cifs_max_pending);
                       cifs_num_waiters_dec(server);
                       spin_lock(&GlobalMid_Lock);
