From the developers mailing list

Daniel Pouzzner

coregrind/m_syswrap/syswrap-amd64-linux.c and friends have

   LINX_(__NR_inotify_init,  sys_inotify_init),

but it's supposed to be

   LINXY(__NR_inotify_init,	 sys_inotify_init),

(POST(sys_inotify_init) is already properly defined and works right.)

Interestingly, this bug only became apparent with release 3.23.0.  v3.22.0 has
the same behavior around PRE/POST -- no call to POST(sys_inotify_init) -- but
doesn't generate any false positive "already closed" errors.
