Patch by Robert Scheck <robert@fedoraproject.org> for clamav <= 0.98 which adds support for
|
||||
ARM. The syscall is taken from arch/arm/include/asm/unistd.h from the Linux kernel. Without
|
||||
this patch building on (at least) ARMv7 fails like this:

Subject: [PATCH] switch to glibc functions for fanotify
|
||||
|
||||
Switch to glibc functions for fanotify instead of using the incomplete
|
||||
hand-crafted support. It makes possible to build clamav on non-x86
|
||||
Linux architectures.
