Description Luis Chamberlain 2023-12-05 03:22:44 UTC

While doing fstests baseline testing on v6.6-rc5 with kdevops [0] we found that the XFS assertion with:

XFS: Assertion failed: bp->b_flags & XBF_DONE, file: fs/xfs/xfs_trans_buf.c, line: 241


This fails on the following tests and respective sections as defined by XFS configs [1]

Comment 3 Luis Chamberlain 2023-12-05 05:16:18 UTC

Here is an interesting tid bit: I ran generic/251 in a loop on xfs_nocrc_4k and cannot reproduce the assert there after 6693 loops.
