Linux 2.6.27.35

Linux 2.6.27.35

[Greg KH]

I'm announcing the release of the 2.6.27.35 kernel.  All users of the
2.6.27 kernel series are very strongly encouraged to upgrade.

I'll also be replying to this message with a copy of the patch between
2.6.27.34 and 2.6.27.35

The updated 2.6.27.y git tree can be found at:
        git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.27.y.git
and can be browsed at the normal kernel.org git web browser:
        http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.27.y.git;a=summary

thanks,

greg k-h

Greg,

I notice the mismerge of mainline commit
170ebf85160dd128e1c4206cc197cce7d1424705
"bas_gigaset: correctly allocate USB interrupt transfer buffer"
into 2.6.27-stable isn't fixed in this release yet. Is that just
a timing problem, or do you still need anything from me?

Thanks,
Tilman

It was a timing problem, I should be resolving it now and queueing up
the fix for the next .27 release.

thanks for your patience.
