"Only yesterday it felt like the 2.6.30 kernel came out (June 9, 2009 - almost a year ago) and we are already up to 2.6.34 (May 17, 2010) with 2.6.35 patches waiting at the gate like an excited thoroughbred waiting at the post. From 2.6.30 to 2.6.34 there has been a great deal of kernel development that impacts file systems and other aspects of Linux storage. Even if you are using a kernel from a distribution and not 'rolling your own' it is important to understand what has been happening in these kernels and how it can impact your system(s). The reason is that new versions of popular distributions are coming out and you need to understand them. What kernel are they using? Does your distribution have write barriers turned on by default? Does your distribution allow LVM to support write barriers? Does you distribution still support the anticipatory IO scheduler? Inquiring minds want to know but more importantly, we all need to know."
