From e817c2f33efb4aa7f02c98dfab9a5f8ff383ea7e Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Thu, 18 Feb 2016 12:04:08 +0100 Subject: selinux: Don't sleep inside inode_getsecid hook The inode_getsecid hook is called from contexts in which sleeping is not allowed, so we cannot revalidate inode security labels from there. Use the non-validating version of inode_security() instead.
