Hi all,
I've uploaded the conslusions of IO controller Mini-summit 2009 on the
web page. Thanks Fernando for creating the slides.

Thank you to all attendees and thank you to the Linux Foundation Japan
for providing us with a conference venue a
The checkpoint file header now has an 11-character string
containing the name of the active LSM, following the uts
info, and a variable length buffer type conaining LSM-specific
version information (for instance a sha1sum of policy).
Handle these.
Also add a -k (--keeplsm) flag to tell restart to

This patch adds the ability to checkpoint and restore selinux

The LSM name is 'selinux', 'smack', 'tomoyo', or 'dummy'. We
add that to the container configuration section. We also add
a LSM policy configuration section. That is placed after the LSM
name. It is written by the LSM in security_checkpoint_header(),
called during checkpoint container(), and re
This completes the work necessary to make checkpoint/restart of
thousands of epoll items more reliable when higher order kmallocs
would fail. We grab a piece of memory suitable to store a "chunk"
of items for input. Read the input one chunk at a time and add
epoll items for each item in the chunk.
Save/restore epoll items during checkpoint/restart respectively.
kmalloc failures should be dealt with more kindly than just error-out
because epoll is made to poll many thousands of file descriptors.
Subsequent patches will change epoll c/r to "chunk" its output/input
respectively.
Signed-off-by:
Currently we allocate memory to output all of the epoll items in one
big chunk. At 20 bytes per item, and since epoll was designed to
support on the order of 10,000 items, we may find ourselves kmalloc'ing
200,000 bytes. That's an order 7 allocation whereas the heuristic for
difficult allocations,
The only way the preceding loop will terminate is if n already has
this value.

This assumption, of course, is just plain wrong. Look at the wait
system calls, for example. However, w

Fix a leak in /proc dentries and inodes with pid namespaces.
This fix reverts the commit 7766755a2f249e7e0. The leak was reported by
Daniel Lezcano - see http://lkml.org/lkml/2009/10/2/159.
To summarize the thread, when container-init is terminated, it sets the
PF_EXITING flag and then zaps all
20 matches
