[sys-utils/readprofile.c:301]: (warning) scanf without field width limits can crash with huge input data.
[sys-utils/readprofile.c:322]: (warning) scanf without field width limits can crash with huge input data.
The process-selection logic is in add_process_to_namespace:
if (!ns->proc || ns->proc->pid > proc->pid)
ns->proc = proc;
so it's just selecting the lowest PID.

We want to address the case that we have printed the last useful
stats line already within the loop. Avoiding an additional line
"Discarded 0 bytes ..." at the end.
Note there is a behavior change now for the edge cases "-v -l 0" and
"-v -o blksize" where we don't print any stats line anymore. But actually
it's correct, we never make any BLKDISCARD syscall with zero range.
Perhaps we should return error in these cases to help people who always
want to parse stats output on success.

We will see if this makes our "--step" tests reliable.

lscpu currently prints information for CPUs configured in the system.
In case of KVM or other virtualized guest operating systems, this
refers to the virtual system, and bears no relation to the physical
topology of the system.
It would be useful if lscpu could also display the physical topology
info when available:
$ ./lscpu
Architecture: ppc64le
Byte Order: Little Endian
CPU(s): 16
On-line CPU(s) list: 0-15
Thread(s) per core: 1
Core(s) per socket: 1
Socket(s): 16
NUMA node(s): 1
Model: IBM pSeries (emulated by qemu)
Hypervisor vendor: KVM
Virtualization type: para
L1d cache: 64K
L1i cache: 32K
NUMA node0 CPU(s): 0-15
Physical sockets: 2 <<< New
Physical chips: 4 <<< New
Physical cores/chip: 4 <<< New
For now, physical topology information is available on platforms that
support the following RTAS (Real time abstraction service) call provided
by librtas:
rtas_get_sysparm(PROCESSOR_MODULE_INFO).
Currently this call is available to the PowerVM (pHYP) guests on PowerPC.
With a patch propoosed to PowerKVM, this RTAS call would also be available
to PowerKVM guests.
Based on input from Nishanth Aravamudan and Karel Zak.

From v4.4, linux kernel starts to support direct I/O and
AIO to backing file for loop driver, so allow losetup to
enable the feature by using LOOP_SET_DIRECT_IO ioctl cmd.

The libmount provides way how to deal with parsing errors in fstab --
on error callback function is executed and according to the return
libmount manipulate with the malformed line, possible are three
states:
1/ fatal error; all file ignored (callback rc < 0)
2/ recoverable error; malformed line ignored (callback rc > 0)
3/ ignore the error (callback rc == 0)
The 2/ is the default if no callback specified.
Unfortunately our utils uses 3/. The correct way is to use 2/.

We care about /proc/device-tree/compatible content...
The patch also removes unnecessary path_exist(), it seems good enough
to call open() rather than access() + open().
