afs: Add more tracepoints
Add four more tracepoints: (1) afs_make_fs_call1 - Split from afs_make_fs_call but takes a filename to log also. (2) afs_make_fs_call2 - Like the above but takes two filenames to log. (3) afs_lookup - Log the result of doing a successful lookup, including a negative result (fid 0:0). (4) afs_get_tree - Log the set up of a volume for mounting. It also extends the name buffer on the afs_edit_dir tracepoint to 24 chars and puts quotes around the filename in the text representation. Signed-off-by: David Howells <dhowells@redhat.com>
