Subject[patch 0/5] per-zone dirty limits v3
Date
Hi,

this is the third revision of the per-zone dirty limits. Changes from
the second version have been mostly documentation, changelog, and
naming fixes based on review feedback:

o add new dirty_balance_reserve instead of abusing totalreserve_pages
for undirtyable (per-zone) reserves and document the variable and
its calculation (Mel)
o use !ALLOC_WMARK_LOW instead of adding new ALLOC_SLOWPATH (Mel)
o rename determine_dirtyable_memory -> global_dirtyable_memory (Andrew)
o better explain behaviour on NUMA in changelog (Andrew)
o extend changelogs and code comments on how per-zone dirty limits are
calculated, and why, and their proportions to the global limit (Mel, Andrew)
o kernel-doc zone_dirty_ok() (Andrew)
o extend changelogs and code comments on how per-zone dirty limits are
used to protect zones from dirty pages (Mel, Andrew)
o revert back to a separate set of zone_dirtyable_memory() and zone_dirty_limit()
for easier reading (Andrew)

Based on v3.1-rc3-mmotm-2011-08-24-14-08.
