It would help if you could capture generic/269.full, but this is likely a
problem with fsck that I fixed a few weeks ago where we're seeing nbytes of an
inode is wrong, but there's an orphan item so it doesn't matter. This patch
just made it more likely for us to have a still being iput'ed inode after a
transaction commit. Thanks,
Josef
Hi Josef,
I enclose the generic/269.full file for your reference.
