+Subject: [PATCH] lsipc: don't free shm data if no shm id is found
+
+There is a segfault in do_shm_global() when ipc_shm_get_info() return 0 and
+ipc_shm_free_info() is called.
+
+When no shm id is found, the memory allocated in shmds by ipc_shm_get_info() is
+already free when ipc_shm_free_info() is called.
+
+Move ipc_shm_free_info(shmds) inside the if statement where at least one shm id
+is found.
