From 5d6c31910bc0713e37628dc0ce677dcb13c8ccf4 Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Thu, 29 Sep 2016 17:48:42 +0200 Subject: xattr: Add __vfs_{get,set,remove}xattr helpers Right now, various places in the kernel check for the existence of getxattr, setxattr, and removexattr inode operations and directly call those operations. Switch to helper functions and test for the IOP_XATTR flag instead.
