Subject[RFC 0/4] vmalloc enhancements
Date
The patchset contains few changes to the vmalloc code, which are
leading to some performance gains and code simplification.

Also, it exports a number of pages, used by vmalloc(),
in /proc/meminfo.

Patch (1) removes some redundancy on __vunmap().
Patch (2) is a preparation for patch (3).
Patch (3) merges independent 3 metadata allocations into one.
Patch (4) adds vmalloc counter to /proc/meminfo.

Roman Gushchin (4):
mm: refactor __vunmap() to avoid duplicated call to find_vm_area()
mm: separate memory allocation and actual work in alloc_vmap_area()
mm: allocate vmalloc metadata in one allocation
mm: show number of vmalloc pages in /proc/meminfo
