From 146c4ad6ec034a1fbfbf90ba76cb69b6504c374a Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Tue, 13 Jun 2017 16:08:52 +0200 Subject: udf: Use i_size_read() in udf_adinicb_writepage() We don't hold inode_lock in udf_adinicb_writepage() so use i_size_read() to get i_size. This cannot cause real problems is i_size is guaranteed to be small but let's be careful.
