Hi, The helper functions bio_add_XXX_page() returns the length which is unsigned int but the return type of those functions is defined as int instead of unsigned int. This is an attempt to fix the return type of those functions and few callers. There are many places where this fix is needed in the callers, if this series makes it to the upstream I'll convert those callers gradually. Any feedback is welcome. -ck Chaitanya Kulkarni (8): block: fix return type of bio_add_hw_page() block: fix return type of bio_add_pc_page() block: fix return type of bio_add_zone_append_page block: fix return type of bio_add_page() lightnvm: fix variable type pblk-core pscsi: fix variable type pscsi_map_sg btrfs: fix variable type in btrfs_bio_add_page block: fix variable type for zero pages block/bio.c | 20 +++++++++++--------- block/blk-lib.c | 2 +- block/blk.h | 7 ++++--- drivers/lightnvm/pblk-core.c | 3 ++- drivers/target/target_core_pscsi.c | 6 ++++-- fs/btrfs/extent_io.c | 2 +- include/linux/bio.h | 11 ++++++----- 7 files changed, 29 insertions(+), 22 deletions(-) -- 2.24.0
