xfs: refactor the btree cursor allocation logic in xchk_ag_btcur_init Change xchk_ag_btcur_init to allocate all cursors first and only then check if we should delete them again because the btree is to damaged. This allows reusing the sick_mask in struct xfs_btree_ops and simplifies the code. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.

xfs: set inode sick state flags when we zap either ondisk fork In a few patches, we'll add some online repair code that tries to massage the ondisk inode record just enough to get it to pass the inode verifiers so that we can continue with more file repairs. Part of that massaging can include zapping the ondisk forks to clear errors. After that point, the bmap fork repair functions will rebuild the zapped forks. Christoph asked for stronger protections against online repair zapping a fork to get the inode to load vs. other threads trying to access the partially repaired file. Do this by adding a special "[DA]FORK_ZAPPED" inode health flag whenever repair zaps a fork, and sprinkling checks for that flag into the various file operations for things that don't like handling an unexpected zero-extents fork. In practice xfs_scrub will scrub and fix the forks almost immediately after zapping them, so the window is very small. However, if a crash or unmount should occur, we can still detect these zapped inode forks by looking for a zero-extents fork when data was expected. Signed-off-by: Darrick J.

xfs: update health status if we get a clean bill of health If scrub finds that everything is ok with the filesystem, we need a way to tell the health tracking that it can let go of indirect health flags, since indirect flags only mean that at some point in the past we lost some context.
