271	Fibril rwlocks read/write lock switch	Radim Vansa	Jakub Jermář	When a fibril rwlock is already locked for writing and the function fibril_rwlock_read_lock() is called, the rwlock should atomically go to read-only lock state (instead of deadlock error). The similar should happen when the lock is acquired for reading and we want to lock it for writing (just in this case it can temporarily block, of course).	enhancement	closed	minor	0.7.0	helenos/lib/c	mainline	wontfix	fibril synchronization
