13    alloc: Allow disabling memfd usage at runtime with XSHMFENCE_NO_MEMFD=1
14    
15    For thin VMs used for compatibility reasons, it is desirable to directly
16    proxy the X11 protocol between an application running in a VM and an X
17    server running on the host. We can proxy futex wakeups with some watcher
18    code, but we need the futex memory itself to be shared. This works when
19    /dev/shm is mounted with virtiofs with DAX, but cannot work for memfds.
20    
21    Add a XSHMFENCE_NO_MEMFD environment variable that, when set, disables
22    the memfd codepath and falls back to /dev/shm.

388    This splits the futex-specific code out into a separate file so that
389    future versions of the library could use some other underlying primitive.

425    Change fence memory type from 'int32_t' to 'struct shmfence'
426    
427    This will allow other implementations to use alternate
428    representations, as well as providing additional typechecking.

449    Recommended by Automake:
450    http://www.gnu.org/software/automake/manual/automake.html#Headers
451    
452    Also, this header is missing in the lint target $(libxshmfence_la_SOURCES)
453    
454    As a bonus, all other libraries are following this advice.
