Function "print_fdset()" in "strace.c" is used to print the file descriptor
values in "print__newselect()" which prints arguments of syscall _newselect().
Until changes from this patch, this function was printing "," even after the
last value of the fd_set argument. This was changed in this patch

This patch implements strace argument printing functionality for following
syscalls:
*getxattr, lgetxattr, fgetxattr - retrieve an extended attribute value
ssize_t getxattr(const char *path, const char *name, void *value,
size_t size)
ssize_t lgetxattr

*fsync, fdatasync

Structure "struct syscallname" in file "strace.c" is used for "-strace"
to print arguments and return values of syscalls. The last field of
this structure "result" represents the calling function that prints the

Socket ioctls SIOCGSTAMP and SIOCGSTAMPNS, used for timestamping the socket
connection, are defined in file "ioctls.h" differently from other ioctls.
The reason for this difference is explained in the comments above their
definition.
These ioctls didn't have def
From: Filip Bozuta
This series introduces the functionality in strace to print arguments for
ioctls. This is gonna be a useful adittion as it indroduces a good debugging
and diagnostic mechanism for user programs cross compiled for different
architectures.
The first patch in the series
From: Filip Bozuta
This patch implements functionality for strace argument printing for ioctls.
When running ioctls through qemu with "-strace", they get printed in format:
"ioctl(fd_num,0x*,0x*) = ret_value"
where the request code an the ioctl's third

Filip Bozuta (3):
linux-user: Add strace support for printing arguments of
truncate()/ftruncate() and getsid()
linux-user: Add strace support for printing arguments of syscalls used
to lock and unlock memory
linux-user: Add strace support for printing arguments of some
ting format in file "strace.list". Syscall mlock2() is not implemented
in
"syscall.c" and thus it's argument printing is not implemented in this
patch.

int_timeval()" was changed a little so
that it prints the field names beside the values. Syscalls "clock_getres()"
and "clocK_gettime()" have the same number and types of arguments and
thus their print functions "print_clock_ge
