I was so busy with doing "write" development that I totally missed it! Somewhere between 2.6.36 and 2.6.37 my exofs file system stopped to receive any a_ops->readpages() (with "s") calls it only receives the single page read, a_ops->readpage(). Needless to say that things get very slow. In 2.6.36 I can clearly see both members getting called the plural one from read-ahead code. I've reverted the few simple patches that went into 2.6.37 for exofs, but clearly it's not it, because the vector is just not called. I'm now bisecting it, but in an hope that some kind soul can put me out of my misery. So the question is: Is there some new nob that needs to be set so read-head starts working again?
