Commit 63159f5dcccb ("uapi: Use __kernel_long_t in struct mq_attr") changed the types from long to __kernel_long_t, but didn't add a linux/types.h include. Code that tries to include this header directly breaks: /usr/include/linux/mqueue.h:26:2: error: unknown type name '__kernel_long_t' __kernel_long_t mq_flags; /* message queue flags */ This also upsets configure tests for this header: checking linux/mqueue.h usability... no checking linux/mqueue.h presence... yes configure: WARNING: linux/mqueue.h: present but cannot be compiled configure: WARNING: linux/mqueue.h: check for missing prerequisite headers? configure: WARNING: linux/mqueue.h: see the Autoconf documentation configure: WARNING: linux/mqueue.h: section "Present But Cannot Be Compiled" configure: WARNING: linux/mqueue.h: proceeding with the compiler's result checking for linux/mqueue.h... no
