This branch was helpful to find the points where the bkl was acquired recursively, and how it gained bad dependencies once turned into a regular sleeping lock because it makes it analyzable by lockdep. We did some work on this tree (various bkl pushdown and removals, also the removal in reiserfs started there). But this tree is not active currently, although it could still be (and its key piece makes it useful to debug the bkl). But currently, the tree that gathers the work in this area is rt/kill-the-bkl Although it's possible Thomas might choose another name if it's scheduled for .33 ? > Also > git describe 55968ede164ae523692f00717f50cd926f1382a0 > v2.6.31-rc6-4-g55968ed > > Not sure what to make of that either, since my patch was against the > latest linus updated this morning. > > Frederic: what was your method to discover that patch from Thomas? I looked at the rt/kill-the-bkl in my local git :) -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
