• 428e6ce02   Lockdep treats down_write_trylock like regular down_write ... Browse Code »

  This causes constructions like

  down_write(&mm1->mmap_sem);
  if (down_write_trylock(&mm2->mmap_sem)) {
  ...
  up_write(&mm2->mmap_sem);
  }
  up_write(&mm1->mmap_sem);

  generate a lockdep warning about circular locking dependence.

  Call rwsem_acquire() with trylock set to 1.
