It turned out Arjan's patch for rmap14 wasn't safe as vmtruncate calls zap_page_range while holding a spinlock. Guess I'll have to release rmap14b soon ;) Rik -- Bravely reimplemented by the knights who say "NIH". http://www.surriel.com/ http://distro.conectiva.com/ Spamtraps of the month: september@surriel.com trac@trac.org # This is a BitKeeper generated patch for the following project: # Project Name: Linux kernel tree # This patch format is intended for GNU patch command version 2.5 or higher. # This patch includes the following deltas: # ChangeSet 1.688 -> 1.689 # mm/memory.c 1.56 -> 1.57 # # The following is the BitKeeper ChangeSet Log # -------------------------------------------- # 02/09/16 riel@imladris.surriel.com 1.689 # vmtruncate calls zap_page_range() with a spinlock held, so remove # the explicit low latency schedule -- rml # -------------------------------------------- # diff -Nru a/mm/memory.c b/mm/memory.c --- a/mm/memory.c Mon Sep 16 00:05:15 2002 +++ b/mm/memory.c Mon Sep 16 00:05:15 2002 @@ -436,9 +436,6 @@ spin_unlock(&mm->page_table_lock); - if (current->need_resched) - schedule(); - address += block; size -= block; } -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
