Add the following kfuncs to set and remove xattrs from BPF programs: bpf_set_dentry_xattr bpf_remove_dentry_xattr bpf_set_dentry_xattr_locked bpf_remove_dentry_xattr_locked The _locked version of these kfuncs are called from hooks where dentry->d_inode is already locked. Instead of requiring the user to know which version of the kfuncs to use, the verifier will pick the proper kfunc based on the calling hook. Signed-off-by: Song Liu <song@kernel.org> ---
