Hello Akshay,
As Kazu mentioned please try the patch :

Thanks for making the changes we discussed in the v1 review. Otherwise
the patch looks fine to me, so:
Reviewed-by: Bh
the gcc warnings and possible
truncation would be to check the return value provided from snprintf
(well there are other methods like using 'asnprintf' or using
'open_memstream' function to create the FILE object, but these are more
intrusive), so this patch does the same.

The vmcore-dmesg utility has been in usage for several years,
and is pretty stable now.
So its useful now to modify its man page to indicate the same.
Also fix some minor formatting issues.

Hello Ioanna,
Thanks for the patch. I am partially at blame here (and also for
top-posting here) as this failure is caused due to the flipped VA
address space support we have on arm64 architecture now with newer
kernels (>= 5.4.0) due to the addition of larger VA addressing space
features

Now with this patch, I can runs hundreds of repetitive nested kexec

So, I think this is a really good patch and should be applied to stable
