The purpose of these tests is to verify that bcachefs fuse support works as expected, including gathering valgrind errors from the bcachefs executable. To do this, bcachefs is executed from a helper thread in the new util.BFuse class, which goes about setting up and validating the valgrind data as well as making sure the mount has completed sufficiently before the test starts executing. This also includes some basic functionality smoke tests which cover file creation, timestamps, etc. Signed-off-by: Justin Husted <sigstop@gmail.com>
