+Subject: zonefs: fix handling of explicit_open option on mount
+
+From: Damien Le Moal <damien.lemoal@opensource.wdc.com>
+
+commit a2a513be7139b279f1b5b2cee59c6c4950c34346 upstream.
+
+Ignoring the explicit_open mount option on mount for devices that do not
+have a limit on the number of open zones must be done after the mount
+options are parsed and set in s_mount_opts. Move the check to ignore
+the explicit_open option after the call to zonefs_parse_options() in
+zonefs_fill_super().
+
+Fixes: b5c00e975779 ("zonefs: open/close zone on file open/close")
