Subject[RESEND][PATCH 2/3] ntfs: remove i_version handling
Date
From: Jeff Layton <jlayton@redhat.com>

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.
