K.Y.S. >> { Clearly I cannot tell you anything about this that you don't know! Looking at the rules for stable tree patches, this patch does not satisfy the requirement that the patch fix a bug since we are changing the behavior here of the ata driver to accommodate Hyper-V. I don't know how much flexibility you have here for taking patches that improve the general usability of Linux in different environments. All I can say is that It will be nice to have this patch in previous stable releases. }
This is _real_ bug

IMHO, patches "does meet the stable_kernel_rules.txt rules" by _all_ criterias . . .
See info correlated with rules: == Rules on what kind of patches are accepted, and which ones are not, into the "-stable" tree:
{ - It must be obviously correct and tested.
Tested ( but, in early implementaition): Ubuntu 12.04 + OpenSUSE
}
{
- It cannot be bigger than 100 lines, with context.
79 lines + 47 lines }
{ - It must fix only one thing.
Yes
}
{
- It must fix a real bug that bothers people (not a, "This could be a problem..." type thing).
Is real bug: see URLs in my e-mails about problem + see tranlate from Russian language issue described by Maksim Kramarenko: http://lists.debian.org/debian-russian/2012/01/msg00324.html ==
. . .
At the conclusion of the system through the halt or when sending a signal shutdown by ACPI to power down the console fell errors: http://www.k-max.name/wp-content/uploads/2012/01/hyper-v.png
Errors do not interfere with work, but sneaking suspicion about future problems with the hard drive ...
. . .
in general, the source of the problem as follows: After [VVM: turn On in kernel source] Hyper-V modules [compile and start use], a hard disk was determined as 2 with the same UUID.
. . .
Here are screenshots of what is happening: connected to a drive: http://www.k-max.name/wp-content/uploads/2012/01/hdd-e1327750214479.png it is defined as a 2: http://www.k-max.name/wp-content/uploads/2012/01/2hdd.png Naturally, the same UUID: http://www.k-max.name/wp-content/uploads/2012/01/blkid.png That's what tells us the directory / dev: http://www.k-max.name/wp-content/uploads/2012/01/uuid.png

}
{ - It must fix a problem that causes a build error (but not for things marked CONFIG_BROKEN), an oops, a hang, data corruption, a real security issue, or some "oh, that's not good" issue. In short, something critical. - New device IDs and quirks are also accepted.
not related this patch
}
{ - No "theoretical race condition" issues, unless an explanation of how the race can be exploited is also provided. - It cannot contain any "trivial" fixes in it (spelling changes, whitespace cleanups, etc).
No "theoretical" , no "trivial"
}
- It must follow the Documentation/SubmittingPatches rules.
Prepare patches -- this job duty of Microsoft employee
- It or an equivalent fix must already exist in Linus' tree (upstream).
Yes
