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. v2->v1: - rebased on top of current mm tree - switch from atomic to percpu vmalloc page counter RFC->v1: - 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 fs/proc/meminfo.c | 2 +- include/linux/vmalloc.h | 2 + mm/vmalloc.c | 113 +++++++++++++++++++++++++++------------- 3 files changed, 79 insertions(+), 38 deletions(-) -- 2.20.1
