Summary:
- Fixed misspellings of "inject"
- Made user read errors retryable when `FLAGS_inject_error_severity == 1`
- Added compaction read errors when `FLAGS_read_fault_one_in > 0`. These are always retryable so that the DB will keep accepting writes
- Reenabled setting `compaction_readahead_size` in crash test. The reason for disabling it was to "keep the test clean", which is not a good enough reason to skip testing it
Pull Request resolved: https://github.com/facebook/rocksdb/pull/11789
Test Plan:
With https://github.com/facebook/rocksdb/issues/11782 reverted, reproduced the bug:
- Build: `make -j56 db_stress`
- Command: `TEST_TMPDIR=/dev/shm python3 tools/db_crashtest.py blackbox --simple --write_buffer_size=524288 --target_file_size_base=524288 --max_bytes_for_level_base=2097152 --interval=10 --max_key=1000000`
- Output:
```
