Hi!
Just started crafting the posix shm driver, with the following:
- Started with "driver" approach (i.e. not mountable fs), similar to
mqueue.
- Added shm_open and shm_unlink to syscalls (similarly as mq_open).
shm_unlink would *maybe* also work directly through vfs, but at least
shm_open

Hi!
I would like to do the posix shm interface for NuttX (shm_open,
shm_unlink etc.); with the following properties
- Would work in all memory protection modes (flat, protected and kernel).
- In flat it would just "malloc" the memory and share the pointer
w. mmap
- In protected it
