Subject: Likley stupid question on "throttle_vm_writeout"
Date: Mon, 9 Nov 2009 07:15:25 -0800 (PST) [thread overview]

Hi, (please CC me on replies)
I have a likely stupid question on the function "throttle_vm_writeout". Looking at the code I find:
if (global_page_state(NR_UNSTABLE_NFS) +
global_page_state(NR_WRITEBACK) <= dirty_thresh)
break;
congestion_wait(WRITE, HZ/10);
Shouldn't the NR_FILE_DIRTY pages be considered as well?
Cheers
Martin
