Subject: [PATCH] Rename poll.h into vm_poll.h to fix build failure on musl
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

musl libc redirects include of sys/poll.h to poll.h. But since poll.h is
also a local header file, the musl libc header is never included. This
leads to the following build failure:

In file included from asyncsocket.c:73:0:
.../host/i586-buildroot-linux-musl/sysroot/usr/include/sys/poll.h:1:2: warning: #warning redirecting incorrect #include <sys/poll.h> to <poll.h> [-Wcpp]
 #warning redirecting incorrect #include <sys/poll.h> to <poll.h>
asyncsocket.c: In function ‘AsyncTCPSocketPollWork’:
asyncsocket.c:2537:13: error: invalid use of undefined type ‘struct pollfd’
          pfd[i].fd = asock[i]->fd;
             ^
asyncsocket.c:2537:13: error: dereferencing pointer to incomplete type ‘struct pollfd’
asyncsocket.c:2538:13: error: invalid use of undefined type ‘struct pollfd’
          pfd[i].events = read ? POLLIN : POLLOUT;
             ^
asyncsocket.c:2538:33: error: ‘POLLIN’ undeclared (first use in this function); did you mean ‘POLL_IN’?
          pfd[i].events = read ? POLLIN : POLLOUT;

So rename poll.h into vm_poll.h as suggested by srowe in
https://github.com/vmware/open-vm-tools/issues/359#issuecomment-533529956

Fixes:
 - http://autobuild.buildroot.org/results/4f575ef42bbc4387a07e396205052b2da081c64d
