The goal of this patchset is to add large MTU/multicredits support for reading and writing from the CIFS client to servers that support SMB 2.1 and higher versions of the protocol.
The first patch fixes a reconnect bug in reading code. Other patches simplify the read/write code (2-4,7,8,11,13), fix rsize/wsize usage bug on reconnects (5,6,9,12,14,15) and introduce multicredits support (10,16). Changes since v2: 1) patch #3 is refactored; 2) fix missed set_mapping_error() in patch #6; 3) fix missed updating of nr_pages value in patch #7; 4) remove unused offset var in patch #8; 5) add reviewed-by/acked-by tags. Changes since v1: 1) read part is added; 2) several reconnects bug (related to the patchset and not) is fixed; 3) overall patch simplification/refactoring is done.
