o Modify extattr_{set,get}() syscalls so that partial reads and writes
with an error condition such as EINTR, EWOULDBLOCK, and ERESTART,
are reported to the application, not silently conceal. This
behavior was copied from the {read,write}v() syscalls, and is
appropriate there but not here.o Correct a bug in extattr_delete() wherein the LOCKLEAF flag is
passed to the wrong argument in namei(), resulting in some unexpected errors during name resolution, and passing in an unlocked vnode.
