Hi,

I was just looking throught the current 5.4-stable queue and saw that 28553fa992cb28 ('Btrfs: fix race between shrinking truncate and fiemap') is queued. Upstream has a follow-up fix for this: 52e29e331070cd aka 'btrfs: don't set path->leave_spinning for truncate'.

Would be nice to get those in together. I only looked at 5.4, don't know about other queues.

Since that fix just hit upstream, I'm going to remove 28553fa992cb28 from the queue now and work on getting both patches in the next release.

Thanks, but maybe wait until [1] has also hit mainline? It's another fix for 28553fa992cb28.

thanks, Holger

Ok, I think I have this all now queued up properly for 5.4.y and 5.5.y, but older kernels will need backports. Can someone send those series of patches to stable@vger.kernel.org if it is needed in older kernels like the commit says they are needed?

thanks,
