[PATCH RFC] vz extension: vzlist, ctid, vzps commands
by Vasily Averin
vz extension contains OpenVZ specific commands:
vzlist shows list of OpenVZ containers,
vzps shows all tasks executed inside of specified container,
ctid shows ContainerID of given task.

Value of
by Karlsson, Jan
Hi Dave
I was looking in the file arm64.c at function arm64_translate_pte and saw the line:
if (!page_present && (pte & PTE_FILE)) {
I also saw that there are two versions of the value PTE_FILE (see also defs.h) and the following code is included in arm64.c in arm64_init:
if (THIS_KERNEL_VERSION >= LINUX(3,10,0)) {
machdep->machspec->pte_protnone = PTE_PROT_NONE_3_10;
machdep->machspec->pte_file = PTE_FILE_3_10;
} else {
machdep->machspec->pte_protnone = PTE_PROT_NONE;
machdep->machspec->pte_file = PTE_FILE;
}
So should not the first mentioned line be changed to:
if (!page_present && (pte & machdep->machspec->pte_file)) {

[PATCH 1/1] CLI list command, print deep structure members
by Alexandr Terekhov
Hi Dave,
I found it useful to be able listing structure's fields which are resided deeper than the first level:
crash> list super_block.s_list -s super_block.s_id,s_dquot.info[1].dqi_dirty_list,s_dquot.dqonoff_mutex.count.counter -H 0xc0a9c800

s_id = "sysfs\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000",
s_dquot.info[1].dqi_dirty_list = {
next = 0x0,
prev = 0x0
},
s_dquot.dqonoff_mutex.count.counter = 1
de805800
s_id = "rootfs\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000",
s_dquot.info[1].dqi_dirty_list = {
next = 0x0,
prev = 0x0
},
s_dquot.dqonoff_mutex.count.counter = 1
Here is a draft patch which contains corresponding logic.
I will appreciate your comments and suggestions.

[PATCH v2] kmem: Introduce -m option
by Aaron Tomlin
Hi Dave,
Hopefully this is satisfactory:
The dump_mem_map() function displays basic data about each entry in the
mem_map[] array, or if an address is specified, just the mem_map[] entry
for that address.
This patch introduces the -m option to be used with 'kmem -p' exclusively.
When used with -p, a comma-separated list of one or more struct page
members may be specified to generate a custom, formatted display. For
example:
crash> kmem -p -m mapping,index,_mapcount.counter,_count.counter
ffffea0000000000 0x0 0 0 0
ffffea0000000040 0x0 0 -1 1
ffffea0000000080 0x0 0 -1 1
ffffea00000000c0 0x0 0 -1 1
ffffea0000000100 0x0 0 -1 1
ffffea0000000140 0x0 0 -1 1
ffffea0000000180 0x0 0 -1 1
ffffea00000001c0 0x0 0 -1 1

[PATCH] kmem: introduce -m option
by Aaron Tomlin
The dump_mem_map() function displays basic data about each entry in the
mem_map[] array, or if an address is specified, just the mem_map[] entry
for that address. This patch introduces the -m option to be used with
'kmem -p' exclusively. When used with -p, a comma-separated list of one or
more struct page members may be specified to generate a custom, formatted
display. For example:
crash> kmem -p -m mapping,index,_mapcount.counter,_count.counter
ffffea0000000000 0x0 0 0 0
ffffea0000000040 0x0 0 -1 1
