Subject: security/commoncap: Use xattr security prefix len
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c5eaab1d131d0a6272df7d55a971a67400d63f56;p=linux.git

security/commoncap: Use xattr security prefix len

Using the existing defined XATTR_SECURITY_PREFIX_LEN instead of
sizeof(XATTR_SECURITY_PREFIX) - 1. Pretty simple cleanup.
