+Subject: [PATCH libaio] harness: Disable failing test 23
+
+This new test fails on several architectures. But it is a new test
+intended to check for a Linux kernel regression, so we are not worse
+off than were before. Add it to the EXTRACASES variables, which has
+currently the side effect of disabling it, as it is not handled
+explicitly in the make target responsible for that variable.

+Subject: [PATCH libaio 02/14] build: Fix DESTDIR and pathname variables
+ handling
+
+The convention for DESTDIR is that it is only prefixed during the
+install target. In this case we postpone that to the inner Makefile
+so that it can be invoked directly while preserving the expected
+semantics. We should also prefer the user specified pathname variables
+if already set in any way, and do not need to pass them explicitly
+to the sub-make.

+
+CPPFLAGS, CFLAGS and LDFLAGS are user flags, which we need to preserve,
+regardless of the user passing them over the environment or the
+command-line. Any required flag that the build system needs, has to be
+set in some other flag (which we will namespace with «MK_») so that the
+build will use even if the user flags are passed, even though the user
+should be able to override by appending after them. We pass CPPFLAGS to
+any compilation command that missed them.

+
+We need to move the SYMVER calls after the function definitions

+Subject: [PATCH libaio 14/14] Fix io_pgetevents() syscall wrapper on 32-bit
+ userland on 64-bit kernels
+
+The kernel compat syscall in the kernel got introduced with a broken
+layout, which requires a pointer to the actual sigset_t variable but
+with the size of the running kernel, not the size of the compat code.
+
+This means that when the wrapper sends the expected compat (32-bit)
+pointer, the kernel reads a 64-bit pointer, eating with it also the
+sigset size member. And then proceeds to fail the comparison of the
+sigset_t size and returns EINVAL.
+
+This really needs to be fixed in the kernel, as there's no apparent
+user of the broken compat layout (from codesearch.debian.org, nor a
+quick github.com search). But we have to workaround it in libaio so
+that we can use kernels that have not yet been fixed.
+
+We do that, by trying the non-broken layout (that would be used with
+a 32-bit userland on a 32-bit kernel), and if that fails with -EINVAL
+we retry with a structure padded to what the kernel expects.
+
