Description of problem: Write&exit command ( 'w' ) in fdisk takes 6 to 8 seconds. Can we have a quick one ? I think the slowness is caused by some sleep() and sync() calls and REREAD_PARTITION ioctls. If this is required for bug^Wbackward compatibility, can we have a new "quick-write&exit" command that does exactly that ?
To get a quick-write&exit command, the best thing to do would be to talk to the upstream maintainer at util-linux.no
