This series marks a few more operations as fast-commit ineligible and accounts them via fc_info so behaviour under fast commit is easier to reason about. Testing was done in a QEMU guest on loopback ext4 filesystems created with -O fast_commit[/,verity] by exercising each operation and checking /proc/fs/ext4/*/fc_info for the corresponding ineligible reason and ineligible commit counters. Detailed steps are in each commit's message.
