From 8f3e2058e1746dc3fb8145f8fbd5ee358cbc1a30 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 20 Jul 2016 11:29:35 +1000 Subject: [PATCH] xfs: don't pass ioflags around in the ioctl path Instead check the file pointer for the invisble I/O flag directly, and use the chance to drop redundant arguments from the xfs_ioc_space prototype.
