Patch series "Some minor cleanup patches resent".
The first three patches trivial clean up patches.
And for the patch "kexec: replace crash_mem_range with range", I got a
ibm-p9wr ppc64le system to test, it works well.
This patch (of 4):
elfcorehdr_alloc() allocates a memory chunk for elfcorehdr_addr with
kzalloc(). If is_vmcore_usable() returns false, elfcorehdr_addr is a
predefined value. If parse_crash_elf_headers() gets some error and
returns a negetive value, the elfcorehdr_addr should be released with
elfcorehdr_free().
This is exceedingly minor - a single memory leak per boot, under very
rare circumstances.
With every patch I merge I consider -stable. Often I'll discuss the
desirability of a backport with the author and with reviewers. Every
single patch. And then some damn script comes along and overrides that
quite careful decision. argh.
Can we please do something like
if (akpm && !cc:stable)
dont_backport()
Yup, I already had it set for 'akpm && mm/ && !cc:stable', happy to
remove the 'mm/' restriction if you're doing the same for the rest of
the patches you review.
And even go further - if your script thinks it might be something we
should backport and if it didn't have cc:stable then contact the
author, reviewers and committers and ask them to reconsider before we
go and backport it. This approach will have the advantage of training
people to consider the backport more consistently.
This is what this mail is all about: I haven't queued up the patch yet,
it gives folks week+ to review, and all it takes is a simple "no" for me
to drop it.
I'd (still) like to have a new patch tag like Not-For-Stable: or
cc:not-stable or something to tell your scripts "yes, we thought about
it and we decided no".
No objections on my part.
