The proper fix would be to use the mmap locking apis defined in include/linux/mmap_lock.h instead. However I would like more information about your report. Did you apply the series yourself ? If so, what base tree did you apply it onto ? If not, what tree did you use that already included the series ? Thanks, -- Michel "Walken" Lespinasse A program is never fully debugged until the last user dies.
