If anyone has any objections, please let me know. ------------------ From: Ryusuke Konishi [ Upstream commit 8e39fbb1edbb4ec9d7c1124f403877fc167fcecd ] In preparation for writing logs, in nilfs_btree_propagate(), which makes parent and ancestor node blocks dirty starting from a modified data block or b-tree node block, if the starting block does not belong to the b-tree, i.e. is isolated, nilfs_btree_do_lookup() called within the function fails with -ENOENT. In this case, even though -ENOENT is an internal code, it is propagated to the log writer via nilfs_bmap_propagate() and may be erroneously returned to system calls such as fsync(). Fix this issue by changing the error code to -EINVAL in this case, and having the bmap layer detect metadata corruption and convert the error code appropriately.
