[Qemu-devel] [PATCH] linux-user: fix problems with inotify syscalls

[Nathan Froyd <froydnj@codesourcery.com>]

The sys_inotify* calls are defined if the target supports them and the
host supports the necessary syscalls.  But the syscalls are handled if
the target supports them.  This situation leads to compilation failures
when the host doesn't support the necessary syscalls, as the linker will
complain about undefined functions.

Fix this state of affairs by making the handling conditions the same as
the call definition conditions.
