From b539b87fed37ffc16c89a6bc3beca2d7aed82e1c Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 2 Sep 2014 14:46:05 -0400 Subject: [PATCH] percpu: implmeent pcpu_nr_empty_pop_pages and chunk->nr_populated pcpu_nr_empty_pop_pages counts the number of empty populated pages across all chunks and chunk->nr_populated counts the number of populated pages in a chunk. Both will be used to implement pre/async population for atomic allocations. pcpu_chunk_[de]populated() are added to update chunk->populated, chunk->nr_populated and pcpu_nr_empty_pop_pages together. All successful chunk [de]populations should be followed by the corresponding pcpu_chunk_[de]populated() calls. Signed-off-by: Tejun Heo --- Reading git-format-patch failed
