ext2 & ext3 lists, Attatched is a patch that allows ext2 and ext3 to link correctly when the kernel is configured with a large NR_CPUS. We do have an immediate need for this patch. Any opinions on this? The per-cpu lists are causing the kmalloc to fail due to allocating more than the max. thanks mh -- Martin Hicks Wild Open Source Inc. mort@xxxxxxxxxxxxxxxxxx 613-266-2296 # 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 1.1356 -> 1.1357 # fs/ext2/super.c 1.55 -> 1.56 # fs/ext3/super.c 1.79 -> 1.80 # # The following is the BitKeeper ChangeSet Log # -------------------------------------------- # 03/11/04 mort@xxxxxxxxxxxxxx 1.1357 # Fix over-sized kmalloc() calls in ext[23]_get_super() when there are # large numbers of processors.
