[PATCH v7 11/28] fsnotify: Pass group argument to free_event

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

 



For group-wide mempool backed events, like FS_ERROR, the free_event
callback will need to reference the group's mempool to free the memory.
Wire that argument into the current callers.
