#     
#     Pull erofs fixes from Gao Xiang:
#      "One patch addresses a null-ptr-deref issue reported by syzbot weeks
#       ago, which is caused by the new long xattr name prefix feature and
#       needs to be fixed.
#     
#       The remaining two patches are minor cleanups to avoid unnecessary
#       compilation and adjust per-cpu kworker configuration.
#     
#       Summary:
#     
#        - Fix null-ptr-deref related to long xattr name prefixes
#     
#        - Avoid pcpubuf compilation if CONFIG_EROFS_FS_ZIP is off
#     
#        - Use high priority kthreads by default if per-cpu kthread workers
#          are enabled"
