From 92ad8f37509a7d9d5dd6e0092211b092a7ca7fb1 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Sun, 6 May 2007 16:12:54 +0300 Subject: UBI: use vmalloc for large buffers UBI allocates temporary buffers of PEB size, which may be 256KiB. Use vmalloc instead of kmalloc for such big temporary buffers.
