I'm dropping LKML from cc, no need to write there if there is a specialized
mailing list.
It looks like the bitmap code in carl9170 needs reviewing. I spotted
one error immediately. bitmap_zero() takes the number of bits, not the
number of long integers.
Chances are not very high that it would help in your case, but here's
the patch. I hope to give carl9170 some good testing before submitting
that patch formally.
carl9170: fix bitmap initialization
From: Pavel Roskin <[email protected]>
bitmap_zero() takes the number of bits, not the long integers used to
keep them.
