Comment 7 for bug 1931660

I've hit this bug on a non-encrypted pool. FS scrub also reported no errors for me. I'm currently on Kernel 5.11.0-37-generic / zfs libs 2.0.2-1ubuntu5.2 (Hirsute), though the corruption may have occurred on a previous kernel / library. The directory which is triggering the hang for me was created Jun 7 of this year so it appears to be recent problem. I've identified the corrupted directory and moved it out of the way (fortunately is contains nothing important), but I'm unable to delete it from the filesystem. Any attempts to read or delete the directory hangs. Setting zfs_recovery=1 does not help. The only way I can recover from hang is to reboot. I'd like to know if there is any way to get rid of the corrupted directory other than having to create a new filesystem and copy over all the other files / dirs except the problem one?
