This patch serial could be divided into two parts.
First three patches refine and adds slab sysfs.
Second three patches rename slab sysfs.
1. Refine slab sysfs
There are four level slabs:
CPU
CPU_PARTIAL
PARTIAL
FULL
And in sysfs, it use show_slab_objects() and cpu_partial_slabs_show() to
reflect the statistics.
In patch 2, it splits some function in show_slab_objects() which makes sure
only cpu_partial_slabs_show() covers statistics for CPU_PARTIAL slabs.
After doing so, it would be more clear that show_slab_objects() has totally 9
statistic combinations for three level of slabs. Each slab has three cases
statistic.
slabs
objects
total_objects
And when we look at current implementation, some of them are missing. So patch
2 & 3 add them up.
2. Rename sysfs
The slab statistics in sysfs are
slabs
objects
total_objects
cpu_slabs
partial
partial_objects
cpu_partial_slabs
which is a little bit hard for users to understand. The second three patches
rename sysfs file in this pattern.
xxx_slabs[[_total]_objects]
Finally it looks Like
slabs
slabs_objects
slabs_total_objects
cpu_slabs
cpu_slabs_objects
cpu_slabs_total_objects
partial_slabs
partial_slabs_objects
partial_slabs_total_objects
cpu_partial_slabs
Wei Yang (6):
mm/slub: add total_objects_partial sysfs
mm/slub: not include cpu_partial data in cpu_slabs sysfs
mm/slub: add cpu_slabs_[total_]objects sysfs
mm/slub: rename ALL slabs sysfs
mm/slub: rename partial_slabs sysfs
mm/slub: rename cpu_partial_slab sysfs
