Subject: [RFC 0/4] vmalloc enhancements
Date: Fri, 14 Dec 2018 10:07:16 -0800 [thread overview]
Message-ID: <20181214180720.32040-1-guro@fb.com> (raw)
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
