Hello,
I'm using release 6.2. I need to do allocations upto
8K which are physically contiguous.
Is m_getjcl the right call for this?
Also, if I use m_getjcl to do 4K allocations, after
two or three allocations I start getting cluster/mbuf
allocation failures; or weird memory corruptions. If I
change it to use MGETCL etc. and do 2K allocations,
the same code works fine.
Is m_getjcl() stable in 6.2? Should I fall back on
implementing my own little backend contig-allocator?
Any response is highly appreciated.
Thanks.
