Its filename was tmpfs-disallow-config_tmpfs_inode64-on-alpha.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Seth Forshee Subject: tmpfs: disallow CONFIG_TMPFS_INODE64 on alpha 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.
