kernel/Documentation/locking/rt-mutex.txt, branch linux-5.1.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-5.1.y2017-08-24T19:38:14Zrtmutex: update rt-mutex2017-08-24T19:38:14ZAlex Shialex.shi@linaro.org2017-07-31T01:50:54Zurn:sha1:68a1e349cecf4e24531cba0f1545a436fa18ee51
The rtmutex remove a pending owner bit in in rt_mutex::owner, in
commit 8161239a8bcc ("rtmutex: Simplify PI algorithm and make highest prio task get lock")
But the document was changed accordingly. Updating it to a meaningful
state.
BTW, as 'Steven Rostedt' mentioned:
There is still technically a "Pending Owner", it's just not called
that anymore. The pending owner happens to be the top_waiter of a lock
that has no owner and has been woken up to grab the lock.
