Hi, This is what I currently have queued up for post merge of the writeback patchset. It contains: - The bdi work allocation and queue cleanup from Christoph. - An sb->s_bdi pointer that gets assigned in get_sb_bdev(), OR from the fs ->fill_super() if the file system doesn't use get_sb_bdev(). It is required for WB_SYNC_ALL writeback. Someone more familiar with this code should check that it is done in the right place. As usual, I'm unsure of NFS... - Once the ->s_bdi is in place, we can get rid of bdi_writeback_all() for WB_SYNC_ALL. WB_SYNC_ALL now has to use bdi_start_writeback(). This cleans up bdi_writeback_all() nicely. - With bdi_writeback_all() only doing WB_SYNC_NONE, we can drop the bdi_lock requirement and move to RCU for bdi_list. Please take a good look and review/comment, thanks! This patchset is based on top of writeback-v20. It boots and works fine for me. fs/btrfs/disk-io.c | 1 fs/fs-writeback.c | 111 ++++++++---------------------------- fs/fuse/inode.c | 2 fs/super.c | 6 + fs/sync.c | 9 ++ fs/ubifs/super.c | 1 include/linux/backing-dev.h | 1 include/linux/fs.h | 1 mm/backing-dev.c | 76 +++++++++++++++++------- mm/page-writeback.c | 8 +- 10 files changed, 105 insertions(+), 111 deletions(-) -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
