[Crash-utility] [PATCH] display MCNT and PRIVATE when using kmem -p

[Qiao Nuohan]

Hello Dave,

I was using ¡®kmem ¨Cp¡¯ to get status of memory. And I could only get
"PAGE PHYSICAL MAPPING INDEX CNT FLAGS" in 2.6.x kernel and later, which
makes me feel the lack of information. So I think of displaying
¡®page._mapcount¡¯ and ¡®page.private¡¯, when using ¡®kmem -p¡¯.

When adding these two items, I found ¡®page._count¡¯ is declared to be
atomic_t whose definition is:

typedef struct {

volatile int counter;

} atomic_t;

However, current crash codes use UINT to get the value of ¡®page._count¡¯.

The first patch (0001-kmem_p_6.0.2.patch) is used to change UINT to INT,
and the second one (0002-kmem_p_6.0.2.patch) will add the items talked
above. Both patches are based on crash 6.0.2.

BTW, I have tested these two patches on RHEL6.2_x86_64, RHEL6.2_i386,
RHEL5.8_x86_64 and RHEL5.8_i386.
