Hi,
I found a bug (maybe) in find_vma function (2.2.0 mm/mmap.c). In original code, find_vma may return mm->mmap_cache directly in wrong case.
Here is patch. ==================== *** linux/mm/mmap.c.org Tue Jan 19 09:24:06 1999 --- linux/mm/mmap.c Wed Jan 27 10:30:42 1999 *************** *** 393,398 **** --- 393,400 ---- } else { /* Then go through the AVL tree quickly. */ struct vm_area_struct * tree = mm->mmap_avl; + + vma = NULL; for (;;) { if (tree == vm_avl_empty) break; ==================== ----- Shinji Sumimoto E-Mail: s-sumi@trc.rwcp.or.jp Real World Computing Partnership
