Announcing a resync and update of BFS for linux kernel 3.14.x:
This is mainly a resync from BFS 0.446, but with the addition of the patches as offered by the generous users as seen in the comments here, Alfred Chen and Oleksandr Natalenko. The changes are to fix a circular locking issue on bootup that rarely hit some people, a fix for kvm soft lockups in SMP mode, and to remove some config options that should not be used with BFS.
What's interesting about working on this latest BFS is that I ran into all sorts of instability due to the new kernel that ironically worked out to be a very serious bug in 3.14.0 and was fixed in 3.14.1 with this patch:
commit 8e58cd80d042569da7af501de897c5e0538d99b0 futex: avoid race between requeue and wake
As is often the case, BFS is exceptional at bringing out race conditions and my machine was almost unusable with any significantly multithreaded application such as firefox which kept hanging. This was a scenario where my delay at syncing up the code worked to my advantage as 3.14.2 is working fine.
So here it is:
Somehow I still forgot to include PF's patch for uniprocessor builds, though it's so uncommon to come across a uniprocessor these days! His patch is still valid and can be grabbed here to be applied on top if you need it:
