Subject: [PATCH 1/1] lib: find_next_bit.o needed by a module only, move it from lib to obj
Date: Thu, 26 Mar 2009 11:22:16 -0400
Message-ID: <> (raw)

It is possible to configure the kernel such that find_next_bit is
referenced only by modules, causing linking to fail with

ERROR: "find_last_bit" [fs/nfs/nfs.ko] undefined!
