stable inclusion from stable-v5.10.122 commit b8c17121f05b542eb6f315a97adbb91060dfb53a category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5W6OE
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
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().
