Hi Greg,

could you please add the above mentioned two patches

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=27d0e5bc85f3341b9ba66f0c23627cf9d7538c9d
reiserfs: fix corruption introduced by balance_leaf refactor


https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=01777836c87081e4f68c4a43c9abe6114805f91e
reiserfs: Fix use after free in journal teardown

in next stable (3.16.3) kernel ?

more and more people seem to be affected by the data corruption
introduced by the recent changes.


Reading through Documentation/stable_kernel_rules.txt,
http://cwe.mitre.org/data/definitions/416.html and
http://www.hpenterprisesecurity.com/vulncat/en/vulncat/cpp/use_after_free.html

both patches seem relevant enough (concerning data integrity
filesystem-wise and security) to be included for the stable branch


Thanks & Regards

Matt
