Subject: [PATCH] tmpfs: Disallow CONFIG_TMPFS_INODE64 on s390
Date: Fri, 5 Feb 2021 17:06:20 -0600 [thread overview]
Message-ID: <20210205230620.518245-1-seth.forshee@canonical.com> (raw)
This feature requires ino_t be 64-bits, which is true for every
64-bit architecture but s390, so prevent this option from being
selected there.
Fixes: ea3271f7196c ("tmpfs: support 64-bit inums per-sb")
Cc: <stable@vger.kernel.org> # v5.9+
