No, not at all, please read Documentation/stable_kernel_patches.txt for
what is acceptable for stable kernel patches.

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

I'll queue this up when I get a chance, there are over 300 patches
pending for the stable kernels right now :(

Also, in the future, always cc stable@vger.kernel.org for any stable
requests so that they don't get lost.

Hi Greg -

27d0e5bc85f3341b9ba66f0c23627cf9d7538c9d

    reiserfs: fix corruption introduced by balance_leaf refactor

    Commits f1f007c308e (reiserfs: balance_leaf refactor, pull out
    balance_leaf_insert_left) and cf22df182bf (reiserfs: balance_leaf
    refactor, pull out balance_leaf_paste_left) missed that the `body'
    pointer was getting repositioned. Subsequent users of the pointer
    would expect it to be repositioned, and as a result, parts of the
    tree would get overwritten. The most common observed corruption
    is indirect block pointers being overwritten.

    Since the body value isn't actually used anymore in the called
routines,
    we can pass back the offset it should be shifted. We constify the body
    and ih pointers in the balance_leaf as a mostly-free preventative
measure.

Should there have been more? I thought it was enough to add the Cc
tag. This one has been in the tree, with the tags and with
"corruption" in the Subject since 13 Aug. I know you're busy but this
seems like a pretty obvious candidate for stable inclusion.
