Revision	Date	Author	Comments
1.13	27-Dec-2017	ozaki-r	Distinguish spin mutex and adaptive mutex on rump kernels for LOCKDEBUG Formerly rump kernels treated the two types of mutexes as both adaptive for LOCKDEBUG for some reasons. Now we can detect violations of mutex restrictions on rump kernels such as taking an adaptive mutex with holding a spin mutex as well as normal kernels.
1.12	15-Feb-2015	justin	branches: 1.12.8; Minor fixes to types and includes
1.11	13-Feb-2015	justin	Whitespace fixes, no functional change
1.10	13-Feb-2015	justin	Fix some return value checks
1.9	29-Dec-2014	justin	Just abort on currently unsupported functions.
1.8	08-Nov-2014	justin	Remove superfluous getcontext()
1.7	08-Nov-2014	justin	Move makecontext into function with getcontext for consistency
1.6	08-Nov-2014	justin	Fix some error handling cases.
1.5	05-Nov-2014	pooka	assert that clock_gettime() does not fail
1.4	24-Aug-2014	pooka	RCS Id police (because we can. or have you heard of git id police?)
1.3	25-Jul-2014	justin	branches: 1.3.2; 1.3.6; Clean up error handling in rumpuser_init()
1.2	22-Jul-2014	justin	Clean up random implementation for librumpuser Use /dev/urandom for platforms without arc4random, not srandom(), deduplicate code, do not read excessive random bytes Reviewed by pooka@
1.1	11-Jul-2014	justin	Add a fiber based implementation of librumpuser in addition to the default pthreads based version. Discussed with pooka@
1.3.6.2	20-Aug-2014	tls	Rebase to HEAD as of a few days ago.
1.3.6.1	25-Jul-2014	tls	file rumpfiber.c was added on branch tls-maxphys on 2014-08-20 00:02:21 +0000
1.3.2.2	10-Aug-2014	tls	Rebase.
1.3.2.1	25-Jul-2014	tls	file rumpfiber.c was added on branch tls-earlyentropy on 2014-08-10 06:52:25 +0000
1.12.8.1	13-Jan-2018	snj	Pull up following revision(s) (requested by ozaki-r in ticket #495): lib/librumpuser/rumpfiber.c: revision 1.13 lib/librumpuser/rumpuser_pth.c: revision 1.46 lib/librumpuser/rumpuser_pth_dummy.c: revision 1.18 sys/kern/kern_condvar.c: revision 1.40 sys/kern/kern_lock.c: revision 1.161 sys/kern/kern_mutex.c: revision 1.68 sys/kern/kern_rwlock.c: revision 1.48 sys/rump/include/rump/rumpuser.h: revision 1.115 sys/rump/librump/rumpkern/locks.c: revision 1.76-1.79 Apply C99-style struct initialization to lockops_t -- Tweak LOCKDEBUG macros (NFC) -- Distinguish spin mutex and adaptive mutex on rump kernels for LOCKDEBUG Formerly rump kernels treated the two types of mutexes as both adaptive for LOCKDEBUG for some reasons. Now we can detect violations of mutex restrictions on rump kernels such as taking an adaptive mutex with holding a spin mutex as well as normal kernels. -- rump: check if the mutex is surely owned by the caller in mutex_exit Unlocking a not-owned mutex wasn't detected well (it could detect if the mutex is not held by anyone but that's not enough). Let's check it (the check is the same as normal kernel's mutex). If LOCKDEBUG is enabled, give the check over LOCKDEBUG because it can provide better debugging information.
