Kernels 2.6.35 and 2.6.36: Storage Updates
Recently, I have spent some time reviewing Linux kernels from a storage perspective; starting with 2.6.30 (actually going back into the 2.6.2x series) and ending with the 2.6.34 kernel. That article was published on June 8 of this year - just a short time ago. In the meantime, the pace of kernel development has continued and as of the writing of this article the merge window for the 2.6.37 kernel has just closed signaling the beginning of the great bug hunt before the release of the 2.6.37 kernel. So now seems like a good time to go over the 2.6.35 and 2.6.36 kernels to review what changes have happened that affect the Linux storage world.
One of the best sources of information about Linux kernel versions is kernelnewbies.org”. It has a very nice writeup of the higher level kernel changes but the writeup can be a little terse. However, they can be very useful as a starting point. In particular, let’s start with the 2.6.35 highlights as a starting point for a discussion about the storage changes in the 2.6.35 kernel.
