Arnd Bergmann 9a311b96c3 hpfs: remove the BKL
This removes the BKL in hpfs in a rather awful
way, by making the code only work on uniprocessor
systems without kernel preemption, as suggested
by Andi Kleen.

The HPFS code probably has close to zero remaining
users on current kernels, all archeological uses of
the file system can probably be done with the significant
restrictions.

The hpfs_lock/hpfs_unlock functions are left in the
code, sincen Mikulas has indicated that he is still
interested in fixing it in a better way.

OS/2 is IBM's operating system for PC's, the same as Warp, and HPFS
is the file system used for organizing files on OS/2 hard disk
partitions. Say Y if you want to be able to read files from and
write files to an OS/2 HPFS partition on your hard drive. OS/2
floppies however are in regular MSDOS format, so you don't need this
option in order to be able to read them. Read
<file:Documentation/filesystems/hpfs.txt>.
To compile this file system support as a module, choose M here: the
module will be called hpfs. If unsure, say N.
