From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Return-Path: From: Amir Goldstein Subject: [PATCH v2 1/3] ovl: disambiguate ovl_encode_fh() Date: Sun, 11 Mar 2018 13:22:52 +0200 Message-Id: <1520767374-19374-2-git-send-email-amir73il@gmail.com> In-Reply-To: <1520767374-19374-1-git-send-email-amir73il@gmail.com> References: <1520767374-19374-1-git-send-email-amir73il@gmail.com> To: Miklos Szeredi Cc: linux-unionfs@vger.kernel.org List-ID: Rename ovl_encode_fh() to ovl_encode_real_fh() to differentiate from the exportfs function ovl_encode_inode_fh() and change the latter to ovl_encode_fh() to match the exportfs method name. Rename ovl_decode_fh() to ovl_decode_real_fh() for consistency.
