* [PATCHv4] mm: Fix calculation of dirtyable memory [not found] <20121112203221.GB4511@redhat.com> @ 2012-11-12 21:35 ` Sonny Rao 2012-11-17 20:41 ` Damien Wyart 2012-11-19 13:40 ` Johannes Weiner 0 siblings, 2 replies; 6+ messages in thread From: Sonny Rao @ 2012-11-12 21:35 UTC (permalink / raw) To: linux-kernel Cc: Fengguang Wu, Peter Zijlstra, Andrew Morton, Michal Hocko, linux-mm, Mandeep Singh Baines, Johannes Weiner, Olof Johansson, Will Drewry, Kees Cook, Aaron Durbin, stable, Sonny Rao, Puneet Kumar The system uses global_dirtyable_memory() to calculate number of dirtyable pages/pages that can be allocated to the page cache. A bug causes an underflow thus making the page count look like a big unsigned number. This in turn confuses the dirty writeback throttling to aggressively write back pages as they become dirty (usually 1 page at a time). This generally only affects systems with highmem because the underflowed count gets subtracted from the global count of dirtyable memory. The problem was introduced with v3.2-4896-gab8fabd Fix is to ensure we don't get an underflowed total of either highmem or global dirtyable memory.

The problem happens mainly when : - running apt-get update (this is a Debian system) : the last phase "reading packages lists" takes *minutes* with disk LED blinking, instead of a few seconds. - installing a kernel generated with kernel-package take also minutes on the "updating grub" step. I am attaching corresponding config. This is a 64-bit system with 6Go of memory and problems arise with memory not used a lot (several gigs of free memory). I guess this should be quite easy to reproduce... Thanks, Damien [-- Attachment #2: config.37 --] [-- Type: application/octet-stream, Size: 61674 bytes --] # # Automatically generated file; DO NOT EDIT. # Linux/x86_64 3.7.0-rc5 Kernel Configuration #

* [PATCHv5] mm: Fix calculation of dirtyable memory 2012-11-19 13:40 ` Johannes Weiner @ 2012-11-19 18:41 ` Sonny Rao 2012-11-19 18:44 ` Sonny Rao 0 siblings, 1 reply; 6+ messages in thread From: Sonny Rao @ 2012-11-19 18:41 UTC (permalink / raw) To: linux-kernel Cc: Fengguang Wu, Peter Zijlstra, Andrew Morton, Michal Hocko, linux-mm, Mandeep Singh Baines, Johannes Weiner, Olof Johansson, Will Drewry, Kees Cook, Aaron Durbin, stable, damien.wyart, Sonny Rao, Puneet Kumar The system uses global_dirtyable_memory() to calculate number of dirtyable pages/pages that can be allocated to the page cache. A bug causes an underflow thus making the page count look like a big unsigned number. This in turn confuses the dirty writeback throttling to aggressively write back pages as they become dirty (usually 1 page at a time). This generally only affects systems with highmem because the underflowed count gets subtracted from the global count of dirtyable memory. The problem was introduced with v3.2-4896-gab8fabd Fix is to ensure we don't get an underflowed total of either highmem or global dirtyable memory.
