From e88d6e10e5c848fd5be8f89e09e3bce2570886b7 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Wed, 29 Aug 2007 14:51:52 +0300 Subject: [PATCH] UBI: do not use vmalloc on I/O path Similar reason as in case of the previous patch: it causes deadlocks if a filesystem with writeback support works on top of UBI. So pre-allocate needed buffers when attaching MTD device. We also need mutexes to protect the buffers, but they do not cause much contantion because they are used in recovery, torture, and WL copy routines, which are called seldom.
