Amir Goldstein 5b02bfc1e7 ovl: do not encode lower fh with upper sb_writers held ... When lower fs is a nested overlayfs, calling encode_fh() on a lower directory dentry may trigger copy up and take sb_writers on the upper fs of the lower nested overlayfs. The lower nested overlayfs may have the same upper fs as this overlayfs, so nested sb_writers lock is illegal. Move all the callers that encode lower fh to before ovl_want_write().
