found by stress test on latest mainline kernel (no more regression out
compared with older kernels for more than a week)
One additional patch updates sub-entries in MAINTAINERS.
Summary:
- Fix error handling in erofs_read_superblock
- Fix locking in erofs_get_meta_page
- Fix inplace behavior due to decompression frontend cleanup
- Update sub-entries in MAINTAINERS in order to better blame"
