First patch separates super block validity check from nilfs_commit_super, and moved the function into callers. Second patch introduces nilfs_set_log_cursor to advance log cursor for one specified super blocks. changes from v2 - restore super block in nilfs_prepare_super - introduce nilfs_set_error * used in nilfs_error - introduce nilfs_set_log_cursor instead of write_log_cursor * instead of writing error, set log cursor to specified sb pointer * used followed by nilfs_commit_super - introduce ns_sbwcount * swap super blocks based on the counter * swap all most all the time, still asymmetric(9:7 ratio) - delete ns_sbwtime[2] * introduce ns_sbwtime instead of array of both super blocks - synchronize super blocks when mount/remount - abandon NILFS_SB_SET_FN * only used in nilfs_set_error, so assign directly in the function - misc style fix - misc comment fix changes from v1 - change macro name NILFS_SUPER_SET_FN -> NILFS_SB_SET_FN * change inline function name as nilfs_sb_set_##name - introduce enum for nilfs_commit_super and nilfs_sync_super * NILFS_SB_COMMIT and NILFS_SB_COMMIT_ALL * use flag instead of dupsb in nilfs_commit_super/sync_super fs/nilfs2/nilfs.h | 11 +++ fs/nilfs2/segment.c | 9 ++- fs/nilfs2/super.c | 187 +++++++++++++++++++++++++++++++++--------------- fs/nilfs2/the_nilfs.c | 17 +++-- fs/nilfs2/the_nilfs.h | 17 ++--- 5 files changed, 163 insertions(+), 78 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-nilfs" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
