[PATCH] lockdep: annotate blkdev nesting ...
Teach special (recursive) locking code to the lock validator.
Effects on non-lockdep kernels:
- the introduction of the following function variants:
extern struct block_device *open_partition_by_devnum(dev_t, unsigned);
extern int blkdev_put_partition(struct block_device *);
static int
blkdev_get_whole(struct block_device *bdev, mode_t mode, unsigned flags);
which on non-lockdep are the same as open_by_devnum(), blkdev_put()
and blkdev_get().
- a subclass parameter to do_open(). [unused on non-lockdep]
- a subclass parameter to __blkdev_put(), which is a new internal
function for the main blkdev_put*() functions. [parameter unused
on non-lockdep kernels, except for two sanity check WARN_ON()s]
these functions carry no semantical difference - they only express
object dependencies towards the lockdep subsystem.
