How are people to test this? "does it boot"?
I've been running kernels with Gerry's 5 patches applied for 11 days
now. This is on a 64bit laptop but with a 32bit kernel + HIGHMEM. I
joined the conversation because my laptop would not resume from suspend
to disk - it either froze or rebooted. With the patches applied the
laptop does successfully resume and has been stable.
Since Monday, I have have been running a kernel with the patches (plus,
from today, the patch you mailed yesterday) applied to 3.7rc7, without
problems.
I've been running 3.7-rc7 with the patches listed below for a week now
and it has been perfectly stable. In particular, my laptop will now
successfully resume from suspend to disk, which always failed without
the patches.
From Jiang Liu:
1. [RFT PATCH v2 1/5] mm: introduce new field "managed_pages" to struct zone
2. [RFT PATCH v1 2/5] mm: replace zone->present_pages with
zone->managed_pages if appreciated
3. [RFT PATCH v1 3/5] mm: set zone->present_pages to number of existing
pages in the zone
4. [RFT PATCH v2 4/5] mm: provide more accurate estimation of pages
occupied by memmap
5. [RFT PATCH v1 5/5] mm: increase totalram_pages when free pages
allocated by bootmem allocator
From Andrew Morton:
6. mm-provide-more-accurate-estimation-of-pages-occupied-by-memmap.patch
Tested-by: Chris Clayton <chris2553@xxxxxxxxxxxxxx>
Thanks.
I have only two of these five patches queued for 3.8:
mm-introduce-new-field-managed_pages-to-struct-zone.patch and
mm-provide-more-accurate-estimation-of-pages-occupied-by-memmap.patch.
I don't recall what happened with the other three.
Gerry posted version 1 of the five patches on 18 November. Version 2 of
the first and fourth patches were posted on 21 November.
BTW, the title of Andrew's patch that I applied is wrong above. It
should be
mm-provide-more-accurate-estimation-of-pages-occupied-by-memmap-fix.
