Subject: [PATCH 03/24] ntfs: remove i_version handling
Git-commit: 7a11ac289c437cb06633620940b191a63dec1f4a
Patch-mainline: v4.16-rc1
References: bsc#1081186

NTFS keeps track of the i_version counter here, seemingly for no reason.
It does not set the SB_I_VERSION flag so it'll never be incremented on
write, and it doesn't increment it internally for metadata operations.
