Quoting David Howells (dhowells@xxxxxxxxxx): > Create a dynamically sized pool of threads for doing very slow work items, such > as invoking mkdir() or rmdir() - things that may take a long time and may > sleep, holding mutexes/semaphores and hogging a thread, and are thus unsuitable > for workqueues. > > The number of threads is always at least a settable minimum, but more are > started when there's more work to do, up to a limit. Because of the nature of > the load, it's not suitable for a 1-thread-per-CPU type pool. A system with > one CPU may well want several threads. > > This is used by FS-Cache to do slow caching operations in the background, such > as looking up, creating or deleting cache objects. > > Signed-off-by: David Howells <dhowells@xxxxxxxxxx> Acked-by: Serge Hallyn <serue@xxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
