  "message": "Add READ_ONCE and WRITE_ONCE (XCC)\n\nThese aren\u0027t quite the same as Linux\u0027s, in that they don\u0027t handle\nstructs.  Currently we don\u0027t need that, especially in a kernel header.\nThe thing we do need is the atomicity of writes of size up to uintptr_t.\n\nThere are places on both the user and kernel sides where we expect\nwrites to be done atomically, and not torn or otherwise mucked with by\nthe compiler.\n\nReinstall your kernel headers.\n\nSigned-off-by: Barret Rhoden \u003cbrho@cs.berkeley.edu\u003e\n",
