Return an empty string when the location is unknown instead of the
string "unknown". This ensures that all location entries are of
the form key=val.

Increase buffer size for the string representation of n_time

ICMP timestamp is a 32-bit number. In pr_ntime(), number of minutes
and seconds is always 2 characters wide. Max. number of hours is 4
characters wide. The buffer size should be at least:

4 + 2 + 2 + 1 (':') + 1 (':') + 1 ('\0') = 11

nd_buf is used to buffer headers (for both the kernel dump itself and
for EKCD) before the final call to netdump_dumper(), which flushes
residual data in nd_buf.  As a result, a small portion of the residual
data would be corrupted.  This manifests when kernel dump compression
is enabled since both zstd and zlib detect the corruption during
decompression.

ti,dual-volt property say that the eMMC support 1.8V and 3.3V not 3.0V
Use the correct caps for the mmc stack.
Note that the MMCHS_SD_CAPA register can only be written once after bootup
so if one is using a u-boot compiled with eMMC support (this is the default)
this code is a no-op but just in case someone have u-boot compiled without
eMMC support this make eMMC works when the kernel is booted.

The fdt node for this driver is a simple-mfd and syscon compatible one
meaning that simplemfd will be the driver attached for it. The gpio driver
is attached to the 'gpio' subnode so use syscon_get_handle_default to
obtain the handle of the syscon from the parent device and use this
to read/write to the memory region.

Some socket options require root privileges to set.  The old code did indeed

fs-specific part of vfs_statfs routines only fill in small portion of the
structure. Previous code was always copying everything at a higher layer to
acoomodate it and this patch does the same.

'df' (no arguments) worked fine because the caller uses mnt_stat itself as the
target buffer, making all the copying a no-op for its own case.
'df /' and similar use a different consumer which passes its own buffer and
this is where you can run into trouble.

This is similar to checks for td_sx_slocks and td_rw_rlocks.
Although td_lk_slocks is an implementation detail, it still makes sense
to validate it.

Inform D that C executed procctl(PROC_PDEATHSIG_CTL).  Otherwise D
might allow B to exit before C is set up to receive a signal on the
parent exit.  In this case, C waits forever for the signal and test
hangs.

ptrace(PT_DETACH) requires stopped debuggee, otherwise it fails.  When
the call fails, the C process is left as debuggee of the process D,
and might be killed too early if process D exits occurs fast enough.

Since pipes are not closed in the forked children, this resulted in
the test hanging, since no write occured from C to wake A.
