[GitHub] [incubator-nuttx] patacongo opened a new pull request #3182: Continue development of Userspace pthread callbacks.
patacongo opened a new pull request #3182:
URL: https://github.com/apache/incubator-nuttx/pull/3182
## Summary
1. Move pthread_exit() to user-space (at libs/libc/pthread/pthread_exit.c). The old pthread_exit is renamed nx_pthread_exit(). Initially, the userspace pthread_exit() only calls nx_pthread_exit() but will eventually perform pthread clean up and data destructor calls.
## Impact
## Testing

From PR #3170
I am beginning to think that the best way to implement per-process globals might be the same way that we already implement other per-process, application data like file descriptor, streams, etc. Allocate then with umm_malloc(), but retain them in the group structure with the system call to access them.

Yes, it's another approach, but why not move all pure userspace stuff to the main stack? So we don't have to put some special FILE function inside the kernel space.

I am not going to complete this change. I am not enjoying having all of my designs being micromanaged in this way and other than enjoyment, I have no motivation to do any of this.
