- Replace BKL with superblock lock in fat/msdos/vfat · 8f593427
  Linus Torvalds authored May 19, 2008
```
This replaces the use of the BKL in the FAT family of filesystems with the
existing superblock lock instead.

The code already appears to do mostly proper locking with its own private
spinlocks (and mutexes), but while the BKL could possibly have been
dropped entirely, converting it to use the superblock lock (which is just
a regular mutex) is the conservative thing to do.

As a per-filesystem mutex, it not only won't have any of the possible
latency issues related to the BKL, but the lock is obviously private to
the particular filesystem instance and will thus not cause problems for
entirely unrelated users like the BKL can.

- Remove the lock_kernel() call from chrdev_open() · 9514dff9
  Jonathan Corbet authored May 18, 2008
```
All in-kernel char device open() functions now either have their own
lock_kernel() calls or clearly do not need one.
