  "message": "Create a dynamically sized pool of threads for doing very slow work items\n\nCreate a dynamically sized pool of threads for doing very slow work items, such\nas invoking mkdir() or rmdir() - things that may take a long time and may\nsleep, holding mutexes/semaphores and hogging a thread, and are thus unsuitable\nfor workqueues.\n\nThe number of threads is always at least a settable minimum, but more are\nstarted when there\u0027s more work to do, up to a limit.  Because of the nature of\nthe load, it\u0027s not suitable for a 1-thread-per-CPU type pool.  A system with\none CPU may well want several threads.\n\nThis is used by FS-Cache to do slow caching operations in the background, such\nas looking up, creating or deleting cache objects.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nAcked-by: Steve Dickson \u003csteved@redhat.com\u003e\nAcked-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nTested-by: Daire Byrne \u003cDaire.Byrne@framestore.com\u003e\n",
