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()
