Subject: Re: PATCH: 2.5.40 sane minimum proc count
Date: Mon, 7 Oct 2002 14:27:00 +0100 [thread overview]
Message-ID: <20021007142700.I18545@parcelfarce.linux.theplanet.co.uk> (raw)
max_threads = mempages / (THREAD_SIZE/PAGE_SIZE) / 8;
- init_task.rlim[RLIMIT_NPROC].rlim_cur = max_threads/2;
- init_task.rlim[RLIMIT_NPROC].rlim_max = max_threads/2;
+ /*
+ * we need to allow at least 10 threads to boot a system
+ */
+ init_task.rlim[RLIMIT_NPROC].rlim_cur = max(10, max_threads/2);
+ init_task.rlim[RLIMIT_NPROC].rlim_max = max(10, max_threads/2);
why not simply:
max_threads = mempages / (THREAD_SIZE/PAGE_SIZE) / 8;
+ /* we need to allow at least 20 threads to boot a system */
+ if (max_threads < 20)
+ max_threads = 20;
+
init_task.rlim[RLIMIT_NPROC].rlim_cur = max_threads/2;
init_task.rlim[RLIMIT_NPROC].rlim_max = max_threads/2;
i think we're going to see more kernel threads with 2.5 than we did with 2.4;
let's be safer.
