++/*
++ * Old kernels (before 2.6.36) were defining XATTR_NAME_CAPS in
++ * <linux/capability.h>, but using XATTR_SECURITY_PREFIX and
++ * XATTR_CAPS_SUFFIX which were defined in the kernel-only part of
++ * <linux/xattr.h>.
++ *
++ * In kernel 2.6.36 (commit af4f136056c984b0aa67feed7d3170b958370b2f),
++ * the XATTR_NAME_CAPS definition was moved to the kernel-only part of
++ * <linux/xattr.h>. It's only in kernel 3.0 (commit
++ * 1dbe39424a43e56a6c9aed12661192af51dcdb9f) that <linux/xattr.h> was
++ * fixed to expose XATTR_NAME_CAPS and the related definitions to
++ * userspace.
++ *
++ * In order to cope with kernels < 3.0, we define here the appropriate
++ * values, which we assume haven't changed over history.
