doing this in every filesystem ->ioctl is a really bad idea. We need to add common handling for ext2-style file attributes first. Also please add a file_readonly() helper - when introduced it only checks IS_RDONLY(file->f_dentry->d_inode) and once you add per-mount flags it only needs to be added in a single place. Actually probably a lowelevel one taking inode,vfsmount and wrappers for a struct file * or struct nameidata * which would cover most of the cases. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
