[Bug 56] New: super-long erroneous timeouts in conntrack table (semantics of list_del() change)
...ipt_REDIRECT, and after upgrading
to 2.4.20, found that conntrack table overflows after a week or so.
Quick examination showed large number of entries in SYN_SENT state
with super long timeouts exist. The offending change was in
include/linux/list.h. list_del() now zeros prev and next pointer of
list_head, which circumvents is_confirmed() test.
This didn't cause troubles to most conntrack entries which disappear
by timing out. But as our cache was bypassing some of the
connections, the machine was seeing only one way stream of packets
(!IPS_SEEN_REPLY). And when the originating host terminat...

[PATCH v3 0/5] iommu: Implement generic_iommu_put_resv_regions()
From: Thierry Reding <treding at nvidia.com>
Most IOMMU drivers only need to free the memory allocated for each
reserved region. Instead of open-coding the loop to do this in each
driver, extract the code into a common function that can be used by
all these drivers.
Changes in v3:
- add Reviewed-by from Jean-Philippe Brucker on virtio patch
- add Acked-by from Will Deacon on ARM SMMU patch

...t of groups into every share list and incur large

{
struct sys_userlist *list_head = NULL;
struct group *gptr;
