I've gone through all the code in the kernel that
uses the big kernel lock and come up with a solution
that seems at least half-reasonable for each of them.
The decisions are somewhat arbitrary, but here is
what I'd suggest we do:
* Remove in 2.6.39:
i830, autofs3, smbfs
* Move to staging now, kill in 2.6.41 (or later):
appletalk, hpfs
* Work around in an ugly way, but keep alive:
* ufs, ipx, i810, cx25721
* Fix properly:
* usbip, go7007, adfs, x25
Some of the patches are rather tricky and I haven't
really done much proper testing, so I'd much prefer
the maintainers to pick up the patches and do the
necessary testing where possible, or even come up
with a better solution.
Arnd Bergmann (20):
drm/i810: remove the BKL
drm: remove i830 driver
staging/usbip: convert to kthread
staging/cx25721: serialize access to devlist
staging/go7007: remove the BKL
staging: Remove autofs3
staging: remove smbfs
adfs: remove the big kernel lock
hpfs: rename big kernel lock to hpfs_lock
hpfs: replace BKL with a global mutex
hpfs: move to drivers/staging
x25: remove the BKL
appletalk: move to staging
staging/appletalk: remove the BKL
ufs: remove the BKL
ipx: remove the BKL
tracing: don't trace the BKL
rtmutex-tester: remove BKL tests
drivers: remove extraneous includes of smp_lock.h
BKL: That's all, folks
