Hi Alan,
if you are going to apply patch I saw today morning on linux-kernel
to disable redzoning on SLAB_HWCACHE aligned areas, drop this one into
wastebasket.
If not, please apply this. When CONFIG_DEBUG_SLAB is enbled,
dentries do not live on 16bytes boundary, but on x*8 + 4 :-( So I
can validate only two low bits.
This patch is for 2.4.2-ac13 with applied patch I sent just few
minutes ago.
Urban's smbfs has same problem, as it uses almost same validate
code...
Thanks,
Petr Vandrovec
