SubjectRe: [PATCH 03/45] Make the slow work pool configurable [ver #41]
Quoting David Howells (dhowells@redhat.com):
> Make the slow work pool configurable through /proc/sys/kernel/slow-work.
>
> (*) /proc/sys/kernel/slow-work/min-threads
>
> The minimum number of threads that should be in the pool as long as it is
> in use. This may be anywhere between 2 and max-threads.
>
> (*) /proc/sys/kernel/slow-work/max-threads
>
> The maximum number of threads that should in the pool. This may be
> anywhere between min-threads and 255 or NR_CPUS * 2, whichever is greater.
>
> (*) /proc/sys/kernel/slow-work/vslow-percentage
>
> The percentage of active threads in the pool that may be used to execute
> very slow work items. This may be between 1 and 99. The resultant number
> is bounded to between 1 and one fewer than the number of active threads.
> This ensures there is always at least one thread that can process very
> slow work items, and always at least one thread that won't.
