Thank Andrew. My first bisection attempt went sideways and ended up
pointing at "fs/mpage.c: forgotten WRITE_SYNC in case of data integrity write"
for some reason.
My attempt to understand what data integrity has to do cgroups was unfruitful :(
Thanks,
Sasha

Thank Andrew. My first bisection attempt went sideways and ended up
pointing at "fs/mpage.c: forgotten WRITE_SYNC in case of data integrity write"
for some reason.

Thanks,
Sasha
