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.

I stared at this code for a while and almost deleted it before
understanding crept into my slow brain.  Hopefully this makes life easier
for the next person to happen on it.

Add a bunch of cycle_kernel_lock() calls · f2b9857e

Jonathan Corbet authored May 18, 2008

All of the open() functions which don't need the BKL on their face may
still depend on its acquisition to serialize opens against driver
initialization.  So make those functions acquire then release the BKL to be
on the safe side.
