[f2fs-dev] [PATCH 2/9] Remove bdi_congested() and wb_congested() and related functions

2022-01-26 Thread NeilBrown
These functions are no longer useful as the only bdis that report congestion are in ceph, fuse, and nfs. None of those bdis can be the target of the calls in drbd, ext2, nilfs2, or xfs. Removing the test on bdi_write_contested() in current_may_throttle() could cause a small change in behaviour,
