[PATCH 56/74] libext2fs: various tweaks to the xattr editor APIs

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

 



A few tweaks to the extended attribute editing APIs:

 * Use size_t, not unsigned int, in the new extended attribute editing
   API.

 * Don't expose the _expand() call since there should be no external
   users.
