question regarding the -stable patch queue ?

[Abhijit Karmarkar]

hi,

i am trying to find if a particular upstream commit [1] will appear in
the next -stable release of 2.6.28 kernel.

i see this commit being marked as "-stable candidate". does that mean
it will automatically make it to the next stable release? or should i
submit a patch against the latest 2.6.28 stable series, to have this
patch queued up for next stable release (2.6.28.10). can someone
please advice?

what is the recommend way to do this search ("will upstream patch X be
included in the next stable release")? so i don't bug this list in
future with similar queries.

finally, talking of this particular commit, we have quite a few
machines with such BIOSes and it will be really nice to have this
included in the next stable (2.6.28.10) release. Without this patch,
machines panic in early boot.

thanks!
abhijit


[1] the commit i am specifically interested in is:
===
[upstream commit: 01522df346f846906eaf6ca57148641476209909]

x86, setup: mark %esi as clobbered in E820 BIOS call

Jordan Hargrave diagnosed a BIOS clobbering %esi in the E820 call.
That particular BIOS has been fixed, but there is a possibility that
this is responsible for other occasional reports of early boot
failure, and it does not hurt to add %esi to the clobbers.

-stable candidate patch.
