Kernel

Fwd: [TuxOnIce-devel] hang on hibernation with kernel 2.6.34.1 and TuxOnIce 3.1.1.1
Hi! Since I initially guessed this to be more likely a vanilla kernel than a TuxOnIce bug, I might just ask on kernel mailinglist, whether someone can tell me on where to sort this backtrace. I do not really have an exact idea what subsystem this is. Async I/O? Ciao, Martin ---------- Weitergeleitete... 11 Jul 2010 04:00

[PATCH 2/6] writeback: reduce calls to global_page_state in balance_dirty_pages()
Reducing the number of times balance_dirty_pages calls global_page_state reduces the cache references and so improves write performance on a variety of workloads. 'perf stats' of simple fio write tests shows the reduction in cache access. Where the test is fio 'write,mmap,600Mb,pre_read' on AMD AthlonX2 with 3G... 10 Jul 2010 23:41

[PATCH 3/6] writeback: avoid unnecessary calculation of bdi dirty thresholds
Split get_dirty_limits() into global_dirty_limits()+bdi_dirty_limit(), so that the latter can be avoided when under global dirty background threshold (which is the normal state for most systems).

[PATCH 4/6] writeback: dont redirty tail an inode with dirty pages
This avoids delaying writeback for an expired (XFS) inode with lots of dirty pages, but no active dirtier at the moment. Previously we only do that for the kupdate case.
