Part of my thinking of calling
inode->i_sb->s_op->dirty_inode(inode, I_DIRTY_TIME_EXPIRED);
So that it would be an explicit callback to XFS. So why don't I break
this as two patches --- one which uses I_DIRTY_SYNC, as before, and a
second one which changes calls dirty_inode() with
I_DIRTY_TIME_EXPIRED, and with a change to XFS so that it recognizes
I_DIRTY_TIME_EXPIRED as if it were I_DIRTY_SYNC. If this would then
allow XFS to simplify how it handles VFS tracking, you could do that
in a separate patch.
Does that work? I'll send out the two patches, and if you can
review/ack the second patch, that would be great.
