Subject: [PATCH] vfs: Pass setxattr(2) flags properly

For some reason generic_setxattr() did not pass flags (XATTR_CREATE,
XATTR_REPLACE) to the filesystem specific helper. This caused that
setxattr(2) syscall just ignored these flags.

Fix the bug by passing flags correctly.

 Who's handling VFS changes when Al is away? Andrew?
