Summary: This diff bumps the open call from FUSE to High priority (which is higher than any other blob open request atm). This has shown improvement on the user experience of EdenFS when it's importing many other things from other channels (thrift, etc.) Reviewed By: chadaustin Differential Revision: D20287389 fbshipit-source-id: 319bc44ef8be5c904d7cf0db7cc2f8be28b4760a
