Subject: [PATCH v2] mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf
Date: Mon, 23 Jan 2017 16:11:48 -0700 [thread overview]
Message-ID: <148521301778.19116.10840599906674778980.stgit@djiang5-desk3.ch.intel.com> (raw)
->fault(), ->page_mkwrite(), and ->pfn_mkwrite() calls do not need to take
a vma and vmf parameter when the vma already resides in vmf. Remove the vma
parameter to simplify things.
Signed-off-by: Dave Jiang <dave.jiang@intel.com>

Subject: [PATCH v2] mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf
Date: Mon, 23 Jan 2017 16:11:48 -0700 [thread overview]
Message-ID: <148521301778.19116.10840599906674778980.stgit@djiang5-desk3.ch.intel.com> (raw)
->fault(), ->page_mkwrite(), and ->pfn_mkwrite() calls do not need to take
a vma and vmf parameter when the vma already resides in vmf. Remove the vma
parameter to simplify things.
Signed-off-by: Dave Jiang <dave.jiang@intel.com>
Reviewed-by: Ross Zwisler <ross.zwisler@linux.intel.com>

This patch has received a build success notification from the 0day-kbuild
robot across 124 configs.
v2:
Addressed comment by Ross, removed unintentional white space change.
