Description

Hi,

I've had the following panic on my NAS after checking out our tree and directly starting a build:
No dump is available.

panic: hammer_sync_record_callback: illegal add during inode deletion record 0xffffffe0d21199070
cpuid = 0

The following comment enclose the if where the panic is hit.

  • XXX There may be a case with RECORD_ADD with DELETED_FE set
  • that we currently panic on.

Not sure if that's relevant.

Cheers,
Antonio Huete
