sys_llistxattr() is a wrapper around extattr_list_link() on BSDs, as
defined in libglusterfs/src/syscall.c

sys_llistxattr(path, list, size) -> extattr_list_link(path,

The man page for extattr_list_link() is available at [1].

>From the man page,
     extattr_list_file() returns a list of attributes present in the requested
     namespace. Each list entry consists of a single byte containing the
     length of the attribute name, followed by the attribute name.  The
     attribute name is not terminated by ASCII 0 (nul). The
     extattr_get_file(), and extattr_list_file() calls consume the data and
     nbytes arguments in the style of read(2);
(The *link() syscalls behave the same as the *file() syscalls, expect
they don't follow symlinks)
