Subject: Increase limits for starting writeback of dirty data
|
|
References: bnc#449662
|
|
Patch-mainline: ?
|
|
|
|
Return limits for dirty pages writeback to the numbers from SLES10. This dramatically
|
|
improves performance of workloads dirtying a lot of memory (e.g. simple databases not
|
|
using direct IO) and we're not aware it would harm anything.
