Merge branch 'userns-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace fixes from Eric Biederman: "This is a set of four fairly obvious bug fixes: - a switch from d_find_alias to d_find_any_alias because the xattr code perversely takes a dentry - two mutex vs copy_to_user fixes from Jann Horn - a fix to use a sanitized size not the size userspace passed in from Christian Brauner" * 'userns-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: getxattr: use correct xattr length sys: don't hold uts_sem while accessing userspace memory userns: move user access out of the mutex cap_inode_getsecurity: use d_find_any_alias() instead of d_find_alias()
