The first fix(es) didn't work with the issue reported in [2], which was in turn very similar to that in [1]. Since I didn't know why, I couldn't be sure that the first fix was correct and did not introduce other issues. > Have they been in -next? Nope.

I didn't propose any partial series patch before, for the above reason. > They are all marked as bug fixes, > should they have stable tags? I guess they should, as fixes to bugs that may cause crashes. If there are other rules for these tags, I'm sorry but I'm not aware of them. > All of them, some of them? The only two non-fix patches are non-functional, trivial code improvements made along the way. Submitting a V2. Thanks, Paolo > > -- > Jens Axboe
