Hi,

Fedora got a bug report https://bugzilla.redhat.com/show_bug.cgi?id=1601529
with 4.18-rc4:

Steps to Reproduce:
1.echo 'int f;' | gcc -include linux/aio_abi.h -xc -c - -o /dev/null

Actual results:
/usr/include/asm/signal.h:127:2: error: unknown type name ‘size_t’
   size_t ss_size;
   ^~~~~~
In file included from <command-line>:32:
/usr/include/linux/aio_abi.h:115:2: error: unknown type name ‘size_t’
   size_t  sigsetsize;
   ^~~~~~

Expected results:
no errors, as in Fedora 28 kernel-headers-4.17.4-200.fc28.x86_64)


This looks like the structure that was introduced with 7a074e96dee6
("aio: implement io_pgetevents") . is #include <linux/signal.h>
the correct header? This breaks compilation of nginx
https://bugzilla.redhat.com/show_bug.cgi?id=1597674

Thanks,
