To: linux-kernel, Andrew Morton, torvalds, stable
We (the -stable team) are announcing the release of the 2.6.25.14
kernel.
It contains lots of bugfixes, all over the map. Any users of the 2.6.25
kernel series should upgrade to this version. For details on the fixes,
see the changelog entries and the diffstat below.
I'll also be replying to this message with a copy of the patch between
2.6.25.13 and 2.6.25.14
The updated 2.6.25.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.25.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.25.y.git;a=summary
thanks,
greg k-h
