need help how to debug xfs crash issue xfs_iunlink_remove: xfs_inotobp() returned error 22

[符永涛]

Hi Brian,
What else I'm missing? Thank you.
stap -e 'probe module("xfs").function("xfs_iunlink"){}'

WARNING: cannot find module xfs debuginfo: No DWARF information found
semantic error: no match while resolving probe point
module("xfs").function("xfs_iunlink")
Pass 2: analysis failed.  Try again with another '--vp 01' option.
