Nothing significant that stands out. A number of cleanups and some fixes in error paths. I would expect any changes outside of jfs to have similar effects on the other file systems as well. > Related to this, we're seeing allocation map corruption periodically > on our production servers and if upgrading the kernel would help I > would do so. I don't see anything that I can point to that might fix a bug there. There might still be some undiscovered race condition, or there might have some other bug that has since gotten fixed that wasn't obviously related to your problem. Have you resized any of your file systems? A pretty serious resizing bug was fixed in 2.6.34.
