[PATCH] tmpfs: Disallow CONFIG_TMPFS_INODE64 on s390

From: Seth Forshee
Date: Fri Feb 05 2021 - 23:28:30 EST


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")
