From e0e3d32bb40d28cf57a6a24e1e1d87ef03b913bd Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Wed, 12 Jan 2011 17:00:26 -0800 Subject: [PATCH] befs: don't pass huge structs by value 'struct befs_disk_data_stream' is huge (~144 bytes) and it's being passed by value in fs/befs/endian.h::cpu_to_fsrun(). It would be better to pass a pointer.
