We now check for an error of jffs2_init_1pass_list, which currently always returns 0, so let's see where you change that. Ah, you don't (it's in line 671 in this file). It's only in jffs2_nand_1pass that you do a change, but even there we have a problem: > diff --git a/fs/jffs2/jffs2_nand_1pass.c b/fs/jffs2/jffs2_nand_1pass.c > index 9bad690..885fa3c 100644 > --- a/fs/jffs2/jffs2_nand_1pass.c > +++ b/fs/jffs2/jffs2_nand_1pass.c > @@ -251,6 +251,7 @@ jffs_init_1pass_list(struct part_info *part) > pL->dir.listCompare = compare_dirents; > pL->frag.listCompare = compare_inodes; > #endif > + return 1; When malloc fails, we get no error output. > } > return 0; > } > @@ -806,7 +807,9 @@ jffs2_1pass_build_lists(struct part_info * part) > nand = nand_info + id->num; > > /* if we are building a list we need to refresh the cache. */ > - jffs_init_1pass_list(part); > + if(! jffs_init_1pass_list(part)) > + return 0; > + And the caller fails also, so the user in this case will see no error message and no output. Not good.
