[PATCH 6 of 33] DM Snapshot: consolidate insert_exception functions

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

 



Patch name: dm-snap-consolidate-insert_exception-functions.patch

It is ridiculous to have two 'insert_*exception' functions when one
of the functions already handles both cases.  Consolidating them.
