Hi Lee,

Thanks for your patch. I see we could a little better here.
There are several other checkpatch ERROR msgs in this file.
Care to fix all of those ERRORS within the same patch itself?

./scripts/checkpatch.pl -f fs/ext4/namei.c | sed -n '/ERROR/,/^$/p'

e.g. to list a few of them -
ERROR: do not use assignment in if condition
#1605: FILE: fs/ext4/namei.c:1605:
+               if ((bh = bh_use[ra_ptr++]) == NULL)

ERROR: space required after that ',' (ctx:VxV)
#1902: FILE: fs/ext4/namei.c:1902:
+                       struct buffer_head **bh,struct dx_frame *frame,
                                               ^

ERROR: space required after that ',' (ctx:VxV)
#2249: FILE: fs/ext4/namei.c:2249:
+       de = do_split(handle,dir, &bh2, frame, &fname->hinfo);
                            ^

ERROR: spaces required around that '=' (ctx:VxV)
#2288: FILE: fs/ext4/namei.c:2288:
+       int     dx_fallback=0;
