Subject[PATCH 0/3] vmalloc enhancements
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) separates memory allocation and data initialization
in alloc_vmap_area()
Patch (3) adds vmalloc counter to /proc/meminfo.

- removed bogus empty lines (suggested by Matthew Wilcox)
- made nr_vmalloc_pages static (suggested by Matthew Wilcox)
- dropped patch 3 from RFC patchset, will post later with
some other changes
- dropped RFC

Roman Gushchin (3):
mm: refactor __vunmap() to avoid duplicated call to find_vm_area()
mm: separate memory allocation and actual work in alloc_vmap_area()
mm: show number of vmalloc pages in /proc/meminfo
