[GSoC][PATCH v16 3/9] fsck: make "fsck_error" callback generic

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The "fsck_error" callback is designed to report the objects-related
error messages. It accepts two parameter "oid" and "object_type" which
is not generic. In order to provide a unified callback which can report
either objects or refs, remove the objects-related parameters and add
the generic parameter "void *fsck_report".

Create a new "fsck_object_report" structure which incorporates the
removed parameters "oid" and "object_type". Then change the
corresponding references to adapt to new "fsck_error" callback.
