Bug#317787: kernel-source-2.6.10: md memory leak
Package: kernel-source-2.6.10
Version: 2.6.10-5
Severity: important
Tags: patch
The attached patch against 2.6.10-5, due to Neil Brown, corrects a
problem in 2.6.10 which causes the md driver to leak bios -- eventually
resulting in a OOM condition. The problem appears to have been corrected
upstream for 2.6.11, but my system hates that version :-) so I would
like to see this backported if you release additional 2.6.10 updates. I
have been running this patch on my system for over 4 days with no sign
of the slab growth that was forcing me to reboot a couple times a week
previously.
Thanks,
Scott Bailey
