Revision ad69c389ec110ea54f8b0c0884b255340ef1c736 authored by Seth Forshee on 09 February 2021, 21:42:17 UTC, committed by Linus Torvalds on 10 February 2021, 01:26:44 UTC
As with s390, alpha is a 64-bit architecture with a 32-bit ino_t. With
CONFIG_TMPFS_INODE64=y tmpfs mounts will get 64-bit inode numbers and
display "inode64" in the mount options, whereas passing "inode64" in the
mount options will fail. This leads to erroneous behaviours such as
this:
# mkdir mnt
# mount -t tmpfs nodev mnt
# mount -o remount,rw mnt
mount: /home/ubuntu/mnt: mount point not mounted or bad option.
Prevent CONFIG_TMPFS_INODE64 from being selected on alpha.
