[PATCH 21/25] hfsplus: Call hfsplus_write_begin() and generic_write_end() directly

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

 



There is only one kind of write_begin/write_end aops, so we don't need
to look up which aop it is, just make hfsplus_write_begin() available to
this file and call it directly.
