It looks like there is no way to tell if the curthread already has a rw_lock as reader since we don't store reader's info in the lock, all it tells me is that someone has this lock as a reader right?[00:52:35] *** ipalreadytaken <ipalreadytaken!~ipalready@108-232-26-171.lightspeed.sndgca.sbcglobal.net> has joined #illumos[00:53:27] *** ipalreadytaken <ipalreadytaken!~ipalready@108-232-26-171.lightspeed.sndgca.sbcglobal.net> has quit IRC (Remote host closed the connection)[00:53:35] *** ipalreadytaken <ipalreadytaken!~ipalready@2602:306:ce81:aab0:f557:8a93:2fb6:77c8> has joined #illumos[01:02:57] *** Kelzier <Kelzier!~duka@77.105.27.241> has quit IRC (Read error: Connection reset by peer)[01:03:52] *** trentm <trentm!~Adium@199.58.193.130> has quit IRC (Quit: Leaving.)[01:04:10] *** sanjay <sanjay!~Adium@174-16-243-116.hlrn.qwest.net> has joined #illumos[01:09:22] *** heroux <heroux!sandroco@gateway/shell/insomnia247/x-emnpzaehxxmlvsmf> has quit IRC (Ping timeout: 250 seconds)[01:12:40] *** ahrs <ahrs!~ahrs@46.166.137.194> has quit IRC (Remote host closed the connection)[01:14:40] *** |asp <|asp!~|asp@c-98-198-102-81.hsd1.tx.comcast.net> has quit IRC (Remote host closed the connection)[01:15:08] *** |asp <|asp!~|asp@2601:2c2:c300:51a9:2167:f29f:2b7d:84fa> has joined #illumos[01:18:09] *** pmooney <pmooney!~pmooney@2001:470:1f11:836:391c:6644:8034:c197> has quit IRC (Quit: WeeChat 1.5)[01:18:14] <rmustacc> Alek: The manual page description there is a bit odd, I have to admit. But yes, there's no way to know who has a rw lock for read.[01:18:22] <rmustacc> At least, not from the rwlock itself.[01:19:03] <Alek> ok thanks, that what I thought. You think it's worth it to file a bug to update that man page?[01:19:46] <rmustacc> Well, if you honor the condition that you have to hold the lock before calling it, then it'll always be correct. ;)[01:19:54] <rmustacc> At least, based on what the manual page says.[01:20:01] <rmustacc> So I think it is correct, if you work on that. Just not super useful.[01:20:03] *** |asp <|asp!~|asp@2601:2c2:c300:51a9:2167:f29f:2b7d:84fa> has quit IRC (Ping timeout: 245 seconds)[01:20:16] <rmustacc> But then again, if you find yourself wanting to use rw_read_locked(), I might reconsider.[01:20:58] <Alek> oh yeah I guess if u hold the lock it IS true. Ok thanks[01:22:02] <Alek> last questions.. this doesn't seem true: http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/common/os/rwlock.c#69[01:22:13] <Alek> "A reader will fail if the lock is either owned (in the RW_READER and RW_READER_STARVEWRITER cases)"[01:22:45] <Alek> Isn't the whole point to have concurrent readers? that doesn't make sense[01:23:18] <rmustacc> In general yes -- however RW_READER_STARVEWRITER is a special case that was introduced to allow someone to deal with writer starvation.[01:23:29] <rmustacc> Basically forcing all future readers to block behind a writer getting in.[01:23:38] <rmustacc> Otherwise you could have a livelock for a writer.[01:23:45] <rmustacc> Though the times when that's necessary are rare.[01:24:06] <rmustacc> Or maybe it was the other way around, sorry.[01:24:31] <rmustacc> Yeah, sorry, got things crossed in my head.[01:25:40] <rmustacc> So it's saying that if you're coming in with either of the RW_READER_* values and it is already owned (e.g. write locked), you'll block.[01:26:06] <rmustacc> Alek: That make more sensE?[01:26:08] <rmustacc> *sense[01:27:54] <Alek> ah yes ok. The phrasing there was mixing me up[01:27:56] *** makruger <makruger!~Michael@pool-108-20-232-57.bstnma.fios.verizon.net> has joined #illumos[01:28:13] *** sanjay <sanjay!~Adium@174-16-243-116.hlrn.qwest.net> has quit IRC (Quit: Leaving.)[01:28:38] <Alek> thanks rmustacc[01:30:03] <rmustacc> Sure, no problem.[01:33:22] <Alek> btw this is why I was reading up on it: https://paste.ec/paste/rCbY3Hhr#rSO9Iwz7lqG1+C7G0yo0qEtrWCuE9zq5CWdUvE89jLl[01:33:46] <Alek> recursive rw_enter as a reader here…[01:33:55] <Alek> looks like we need to change this http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/common/fs/zfs/zfs_vnops.c#4387 RW_READER to a RW_READER_STARVEWRITER since I can't think of anything better…[01:36:29] <Alek> deadlock happens if u try to destroy the filesystem between the two reader enters, since we grab the z_teardown_inactive_lock as writer then[01:40:51] <rmustacc> I see. Yeah, recursive rw enters are always tricky.[01:41:03] <rmustacc> Or this is where you have the starvewriter.[01:41:08] <rmustacc> I think Bryan introduced it for a similar reason.[01:43:17] ***
