[PATCH 2/2] message printing cleanup for option --mem-usage

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

So the output is like below now:

~$ ./makedumpfile --mem-usage /proc/kcore 
The kernel version is not supported.
The makedumpfile operation may be incomplete.

TYPE		PAGES			EXCLUDABLE	DESCRIPTION
----------------------------------------------------------------------
ZERO		28247           	yes		Pages filled
with zero
CACHE		240114          	yes		Cache pages
CACHE_PRIVATE	17902           	yes		Cache pages +
private
USER		19713           	yes		User process
pages
FREE		3639969         	yes		Free pages
KERN_DATA	103723          	no		Dumpable kernel
data 

page size:		4096            
Total pages on system:	4049668

That warning won't occur on kernel which makedumpfile declares to
support,  Just notice user the kernel they are using is not tested
yet on compatibility. So it should not be a problem.

Thanks
