error when writing to jffs2 (success in another evb)

[??]

by enabling CONFIG_JFFS2_FS_DEBUG=1
i discover a typo buggy in fs/jffs2/gc.c:
fs/fs.o: In function `jffs2_garbage_collect_hole':
gc.c(.text+0x45c9c): undefined reference to `unlikely'
gc.c(.text+0x45c9c): relocation truncated to fit: R_MIPS_26 unlikely
fixed it by add:
#include <linux/compiler.h>
to fs/jffs2/gc.c for macro<"unlikely">
---success
story----------------------------------------------------------------------
success story: in our evb241x, jffs2 is ported ok

# mount

/dev/ram1 on /var type minix (rw)
# df -h

log---------------------------------------------------------------------
the faulting kernel in our evb13x can't boot today, so log can't send :<
log show: "kernel BUG at traps.c:623!"
(probably hw problem or buggy mips 2.4.17 kernel)
