From ce3077ee80d6ac1087c06441f4c63ce5f13ef12c Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Fri, 23 Feb 2018 13:45:29 +0200 Subject: direct-io: Remove unused DIO_SKIP_DIO_COUNT logic This flag was added by fe0f07d08ee3 ("direct-io: only inc/deci inode->i_dio_count for file systems") as means to optimise the atomic modificaiton of the variable for blockdevices. However with the advent of 542ff7bf18c6 ("block: new direct I/O implementation") it became unused. So let's remove it.
