[CRIU] zdtm/static/fd failure on aarch64

[Adrian Reber]

Hi Dmitry,

following tests are still failing on aarch64 on my setup:

 * zdtm/static/fd(h)
 * zdtm/static/cow01(h)
 * zdtm/transition/maps007(h)

I started to look closer at zdtm/static/fd and it seems to fail while
running the mutex_lock() function:

10:12:24.210:  3813: ERR: ../lib/lock.h:148: futex (errno = 11 (Resource temporarily unavailable))
10:12:24.211:  3812: ERR: test.c:256: Test exited on unexpected signal 6

In strace I see the following:

[pid  3813] futex(0xffff9c140000, FUTEX_WAIT, 2618556417, NULL) = -1 EAGAIN (Resource temporarily unavailable)

So somehow it cannot do the lock and fails.

Any ideas what might be wrong here.

In the code there is mmap(... PAGE_SIZE ...) which is done using the
correct value for that platform.
