From 4bbcc965f995564870ca02606137e60e873e0a1f Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Sat, 9 Sep 2017 13:15:55 -0400 Subject: fs: add fs_readdir() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Needed to support efi file protocol. The fallback.efi loader wants to be able to read the contents of the /EFI directory to find an OS to boot. Modelled after POSIX opendir()/readdir()/closedir(). Unlike the other fs APIs, this is stateful (ie. state is held in the FS_DIR "directory stream"), to avoid re-traversing of the directory structure at each step. The directory stream must be released with closedir() when it is no longer needed.
