Hello, (This is for 3.14-rc1. Posting early for review. Will refresh and repost once the next driver-core-next opens.) kernfs inherited "security.*" xattr support from sysfs but for it to be useable for cgroupfs, it needs to support "trusted.*" too. This patchset adds "trusted.*" xattr support using simple_xattr*(). Note that the existing "security.*" support is gimped in that it doesn't include remove/get/list. This patchset implements all operations for "trusted.*" but doesn't change "security.*" support. David P. Quigley, can you please comment on this? It doesn't seem like adding it would be too difficult. Why don't we have it yet? Are they unnecessary? This patchset contains the following two patches. 0001-kernfs-update-sysfs_init_inode_attrs.patch 0002-kernfs-implement-trusted.-xattr-support.patch 0001 preps and 0002 implements. This patchset is on top of driver-core-next 0cae60f91494 ("sysfs: rename sysfs_assoc_lock and explain what it's about") +  [PATCHSET] sysfs: separate out kernfs, take #2 and available in the following git branch. git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git review-kernfs-xattr diffstat follows.
