#     
#     Pull erofs fixes from Gao Xiang:
#      "Most patches randomly fix error paths or corner cases in fscache mode
#       reported recently. One fixes an invalid access relating to fragments
#       on crafted images.
#     
#       Summary:
#     
#        - Fix packed_inode invalid access when reading fragments on crafted
#          images
#     
#        - Add a missing erofs_put_metabuf() in an error path in fscache mode
#     
#        - Fix incorrect `count' for unmapped extents in fscache mode
#     
#        - Fix use-after-free of fsid and domain_id string when remounting
#     
#        - Fix missing xas_retry() in fscache mode"
