From: Trond Myklebust Date: Thu, 26 Mar 2015 00:40:38 +0000 (-0400) Subject: NFSv4.1/pnfs: Refactor pnfs_set_layoutcommit() X-Git-Tag: v4.1-rc1~6^2~24 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=67af7611ec57dbcbc96f9d9daa4d3c7b0999aa73;p=linux.git NFSv4.1/pnfs: Refactor pnfs_set_layoutcommit() pnfs_set_layoutcommit() and pnfs_commit_set_layoutcommit() are 100% identical except for the function arguments. Refactor to eliminate the difference.
