Revision 7813b94a54987571082ff19e9d87eabbfec23b4e authored by Linus Torvalds on 07 August 2011, 16:53:20 UTC, committed by Linus Torvalds on 07 August 2011, 20:42:25 UTC 
vfs: rename 'do_follow_link' to 'should_follow_link'

misnamed - it's about whether we should try to follow a symlink or not,
not about actually doing the following.
