Re: [Crash-utility] [PATCH v2] kmem: Introduce -m option

Aaron Tomlin and I have been collaborating offline/in-house with respect to this patch, and we've finally come up with an implementation that is queued for crash-7.1.1: https://github.com/crash-utility/crash/commit/a8e7fc1e580122fac032c80f789... - Implemented a new "kmem -m" option that is similar to "kmem -p", but it allows the user to specify the page struct members to be displayed. The option takes a comma-separated list of one or more page struct members, which will be displayed following the page structure address. The "flags" member will always be expressed in hexadecimal format, and the "_count" and "_mapcount" members will always be expressed in decimal format. Otherwise, all other members will be displayed in hexadecimal format unless the current output radix is 10 and the member is a signed/unsigned integer. Members that are data structures may be specified by the data structure's member name, or expanded to specify a member of that data structure. For example, "-m lru" refers to a list_head data structure, in which case both the list_head.next and list_head.prev pointer values will be displayed; if "-m lru.next" is specified, just the list_head.next value will be displayed.
