2007-08-27 Thread Esteban Fernandez
How do you pause the kernel boot messages ? ^S, Pause and Scroll lock do nothing and you can't Shift-Page-Up after a kernel panic. Thanks. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.k

[PATCH 0/3] [RFC][PATCH] clustered writeback

2007-08-27 Thread Fengguang Wu
Chris, This is one possible implementation of the clustered writeback idea. It runs OK on ext3 (compiling, syncing, etc.). The patch is based on 2.6.23-rc3-mm1 and the writeback patches here: http://lkml.org/lkml/2007/8/19/10 By default, with many dirty inodes, it works as follows: - store dirty

[PATCH 2/3] writeback: introduce dirty_volatile_interval

2007-08-27 Thread Fengguang Wu
Introduce dirty_volatile_interval for the minimal dirty time. Inodes dirtied less than dirty_volatile_interval will not be considered for syncing by kupdate-style writeback. This new parameter will be used in clustered writeback. The old dirty_expire_interval is still(but less) respected. Cc: Chr

2007-08-27 Thread Fengguang Wu
Organize dirty inodes in the order of location instead of dirty time. It helps write extensive workloads to be more seek-friendly. There are 2 candidates for this feature: 1) XFS style piggybacking write all expired(age>30s) inodes, plus the ones near them(any ages) 2) e
