Subject: PM / Hibernate: fix the number of pages used for hibernate/thaw buffering
X-Git-Tag: next-20120423~31^2
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fnext%2Flinux-next.git;a=commitdiff_plain;h=e9cbc5a6270be7aa9c42d9b15293ba9ac7161262
PM / Hibernate: fix the number of pages used for hibernate/thaw buffering
Hibernation/thaw fixes/improvements:
1. Calculate the number of required free pages based on non-high memory
pages only, because that is where the buffers will come from.
2. Do not allocate memory for buffers from emergency pools, unless
absolutely required. Do not warn about and do not retry non-essential
failed allocations.
3. Do not check the amount of free pages left on every single page
write, but wait until one map is completely populated and then check.
4. Set maximum number of pages for read buffering consistently, instead
of inadvertently depending on the size of the sector type.
5. Fix copyright line, which I missed when I submitted the hibernation
threading patch.
6. Dispense with bit shifting arithmetic to improve readability.
