This is the second attempt at the patchset to clean up the management
of open filehandles in CIFS. The main changes are:
1) elimination of some more unnecessary NULL pointer checks
2) the cifs_file_list_lock (aka GlobalSMBSeslock) has been left as a
rwlock_t, though it has been renamed as before
3) the order of operations in cifs_oplock_break_put has been fixed --
previously it put the sb reference before the cifsFileInfo reference
which could have led to oopses.
4) cifs_flush only waits for writeback to complete on filehandles that
were opened with FMODE_WRITE set.
The patchset has passed several hours running the connectathon testsuite
in a loop.
Suresh and Shaggy both sent acks for various parts of the patchset, but
the last few patches had enough substantial changes that I didn't want
to add them without their "re-acks".
