/* these five flags used when we are tsleep'ing on a mutex.  There are five spl
mutex'es used in bsd_compat.c.   For each of them we need to mark a flag, if
they are currently being held by us.  When we return from tsleep, we
re-take the spl mutexes based on these flags.  So these flags are not used
for spl mutexes.  They are used for other mutexes that gets called via tsleep
if the thread calling tsleep has taken any of the spl mutexes. 
These flags are also used in a thread context block using one of the
aplication specific thread context variable.  */
