[PATCH 1/2] mm: helper functions for dirty and writeback accounting
Exporting account_pages_dirty and adding a symmetric routine account_pages_writeback. This allows code outside of the mm core to safely manipulate page state and not worry about the other accounting. Not using these routines means that some code will lose track of the accounting and we get bugs. This has happene... 4 Aug 2010 21:16

[PATCH 2/2] writeback: Adding pages_dirtied and pages_entered_writeback
To help developers and applications gain visibility into writeback behaviour adding four read only sysctl files into /proc/sys/vm. These files allow user apps to understand writeback behaviour over time and learn how it is impacting their performance. # cat /proc/sys/vm/pages_dirtied 3747 # cat /proc/s... 4 Aug 2010 21:16
