From f4a8116a4c8c8f754d0ec1498a2ba4b63d114e6a Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Tue, 8 Aug 2017 09:54:36 +0200 Subject: fs: Provide __inode_get_bytes() Provide helper __inode_get_bytes() which assumes i_lock is already acquired. Quota code will need this to be able to use i_lock to protect consistency of quota accounting information and inode usage.
