| H A D | binderfs.c | 9d64d240 Tue Aug 23 04:53:39 CDT 2022 Al Viro <viro@zeniv.linux.org.uk> binderfs: rework superblock destruction
So far we relied on
.put_super = binderfs_put_super()
to destroy info we stashed in sb->s_fs_info. This gave us the required ordering
between ->evict_inode() and sb->s_fs_info destruction.
But the current implementation of binderfs_fill_super() has a memory leak in
the rare circumstance that d_make_root() fails because ->put_super() is only
called when sb->s_root is initialized. Fix this by removing ->put_super() and
simply do all that work in binderfs_kill_super().
