Hmmm... It works okay for me, but then I'm testing it on i686, not x86_64.
Should I draw any meaning from you saying "(on x86_64)"?
Also, can you do:
gdb vmlinux
And then at the prompt, can you disassemble the reiserfs_kill_sb() function:
disas reiserfs_kill_sb
And send me the disassembly?
If I had to guess, I'd say that REISERFS_SB() returned a NULL pointer, and
that sb->s_root is NULL. In which case generic_shutdown_super() will not
invoke reiserfs_put_super().
Something that you can try is to modify reiserfs_kill_sb() to be:
static void reiserfs_kill_sb(struct super_block *s)
{
if (REISERFS_SB(s) {
if (REISERFS_SB(s)->xattr_root) {
d_invalidate(REISERFS_SB(s)->xattr_root);
dput(REISERFS_SB(s)->xattr_root);
REISERFS_SB(s)->xattr_root = NULL;
}
if (REISERFS_SB(s)->priv_root) {
d_invalidate(REISERFS_SB(s)->priv_root);
dput(REISERFS_SB(s)->priv_root);
REISERFS_SB(s)->priv_root = NULL;
}
}
kill_block_super(s);
}
That way the function will be able to kill a superblock that isn't fully
initialised.
