    Subject: [2.4 patch] fix a compile warning in InterMezzo file.c

    I got the following warning in 2.4.23-pre3:

    <-- snip -->

    ...
    gcc-2.95 -D__KERNEL__
    -I/home/bunk/linux/kernel-2.4/linux-2.4.23-pre3-full/inclu
    de -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing
    -fno-common -pipe -mpreferred-stack-boundary=2 -march=k6 -nostdinc -iwithprefix
    include -DKBUILD_BASENAME=file -c -o file.o file.c
    file.c: In function `presto_open_upcall':
    file.c:64: warning: `rc' might be used uninitialized in this function
    ...

    <-- snip -->

    The patch below (already included in 2.6) fixes this warning.

    Please apply
