Dne 16.6.2017 v 18:08 Douglas Miller napsal(a): > Just to respond to James' question on the cause. What I observed was a race condition between udevd (ses_init()) and a worker thread (do_scan_async()), > where the worker thread is creating the directories that are the target of the symlinks being created by udevd. > Something was happening when udevd caught up with the worker thread (so the target directory did not exist) and it seemed the worker thread either got preempted or > else just could not stay ahead of udevd. This means that udevd started failing to create symlinks even though the worker thread eventually got them all created. > I did observe what appeared to be preemption, as the creation of directories stopped until udevd finished failing all the (rest of the) symlinks. > Although there may have been other explanations for what I saw. > > I am able to pass my testing with this patch. I don't see an official submit of this patch, but will respond to it when I see one. Thanks Douglas for testing it, I will resubmit the patch if no one has any objections. Maurizio.
