parentipc/mqueue.c: refactor failure handling (diff)
ipc/mqueue.c: fix mq_open() return value
We return ENOMEM from mqueue_get_inode even when we have enough memory. Namely in case the system rlimit of mqueue was reached. This error propagates to mq_queue and user sees the error unexpectedly. So fix this up to properly return EMFILE as described in the manpage: EMFILE The process already has the maximum number of files and message queues open. instead of: ENOMEM Insufficient memory. With the previous patch we just switch to ERR_PTR/PTR_ERR/IS_ERR error handling here.
