[LTP] [PATCH 0/3] syscalls/aio: Convert libaio wrapper function to kernel syscall

[xieziyao]

Hi, Petr, Jan,

I am working on adapting the new API to the testsuite of syscalls/io_*.

At the same time, I prefer to replace libaio wrapper function with raw system call(tst_syscall(__NR_io_*)) just for the aio testcases of kernel/syscalls, since this method may be more straightforward, no need to rely on other libraries.

Glad to see your discussion and participation, thanks.

Kind regards,
Ziyao

you haven't missed anything. io_destroy(ctx) (libaio.h) is being replaced with
raw syscall (tst_syscall(__NR_io_destroy, ctx).

Kind regards,
Petr
