[PATCH] Remove fcntl f_op
The newly introduced ->fcntl file_operation is badly thought out,
not to mention undocumented. This patch replaces it with two better
defined operations -- check_flags and dir_notify. Any other fcntl()s
that filesystems are interested in can have their own properly typed
f_op method when they need it.
