Next: [PATCH 1/6] writeback: take account of NR_WRITEBACK_TEMP in balance_dirty_pages()
From: Wu Fengguang on 10 Jul 2010 22:40 Andrew, Here are some writeback cleanups to avoid unnecessary calculation overheads, and relative simple bug fixes. The patch applies to latest linux-next tree. The mmotm tree will need rebase to include commit 32422c79 (writeback: Add tracing to balance_dirty_pages) in order to avoid merge conflicts. [PATCH 1/6] writeback: take account of NR_WRITEBACK_TEMP in balance_dirty_pages() [PATCH 2/6] writeback: reduce calls to global_page_state in balance_dirty_pages() [PATCH 3/6] writeback: avoid unnecessary calculation of bdi dirty thresholds [PATCH 4/6] writeback: dont redirty tail an inode with dirty pages [PATCH 5/6] writeback: fix queue_io() ordering [PATCH 6/6] writeback: merge for_kupdate and !for_kupdate cases fs/fs-writeback.c | 68 ++++----------- include/linux/writeback.h | 5 - mm/backing-dev.c | 3 mm/page-writeback.c | 158 ++++++++++++++---------------------- 4 files changed, 89 insertions(+), 145 deletions(-) Thanks, Fengguang -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
