Questions about the SYSVIPC share memory on NOMMU uClinux architecture

Hi folks, Recently, I was struggling in a bug about the shm->nattch. Actually, the test case is from LTP kernel/syscall/ipc/shmctl/shmctl01.c code. We ported it to the uClinux-blackfin platform. The algorithm is very simple. a) the parent process will create a share memory b) parent will
