It's a scary message for something we've always handled, and that we still handle fine, we just complain about it. So we'll probably just turn the message off for 2.6.22, but in the meantime, we leave it on and try to fix as many of these as we can be bothered to.

I'd like to rerun the full set of tests I did before to be sure, but so far so good. No other apparent regressions either. Also, the match between the observed symptoms and the bugfix is very good, which adds confidence (ie, no element of "it works now but we don't know why"). I guess the only remaining concern is whether there are any other paths which fail to dirty the inode. Did you manage to repro the problem? J ^ permalink raw reply [flat|nested] 9+ messages in thread
