Message-Id: <1413281035-6483-1-git-send-email-dmonakhov@openvz.org> Date: Tue, 14 Oct 2014 14:03:51 +0400 From: Dmitry Monakhov <dmonakhov@...nvz.org> To: linux-kernel@...r.kernel.org Cc: Dmitry Monakhov <dmonakhov@...nvz.org> Subject: [PATCH 0/4] blkdev: flush optimization Some filesystems try to optimize barrier flushes by maintaining fs-specific generation counters, but if we introduce generic flush generation counter for block device filesystems may use it for fdatasync(2) optimization. Optimization should works if userspace performs mutli-threaded IO with a lot of fdatasync() TOC: blkdev: add flush generation counter md: add flush_idx support for stacked devices ext4: cleanup data integrity sync fo nonjournal mode ext4: Add fdatasync scalability optimization -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
