Author: cem Date: Fri Apr 21 22:00:22 2017 New Revision: 317273 URL: https://svnweb.freebsd.org/changeset/base/317273 Log: fuse: Implement FOPEN_KEEP_CACHE flag Implement FUSE open flag FOPEN_KEEP_CACHE. Without this flag, cached file contents should be invalidated on open. Apparently, fusefs-encfs relies upon this behavior.
