[Qemu-devel] [PATCH v3 00/13] linux-user: strace improvements

[Philippe Mathieu-Daudé]

Hi Laurent,

Few patches I'v been writting while trying to figure out this issue:
http://lists.nongnu.org/archive/html/qemu-arm/2018-01/msg00514.html

As usual with linux-user files, this series will trigger some checkpatch
benign warnings.

Regards,

Phil.

Since v2:
- display invalid pointer in print_timeval() and print_timezone()
- do not display gettimeofday() arguments

Since v1:
- addressed Laurent comments
- added 'last' argument to print_sockaddr()
- reordered series, so patches already correct can get applied directly
- dropped "linux-user/syscall: simplify recvfrom()" for now

v1: http://lists.nongnu.org/archive/html/qemu-devel/2018-01/msg05855.html
v2: http://lists.nongnu.org/archive/html/qemu-devel/2018-06/msg08216.html
