And it also couldn't be merged until now (5.6-rc1) because it relies on stuff from a few different git trees. (Leon: I added my standard blurb about "this changes set_page_dirty() to set_page_dirty_lock()", to the commit description.) I've reviewed this, and done some basic checks (cross-compiles, and a subset of an LTP run on x86), but I have not personally done directed tests that would provide coverage of this change. For that, could we please get some Tested-by tags, and any other tags (reviews, acks) from those of you who have reportedly tested this? That would be Hans or Santosh (on Cc below), I'm told: Cc: Hans Westgaard Ry Cc: Santosh Shilimkar Leon Romanovsky (1): net/rds: Track user mapped pages through special API net/rds/rdma.c | 24 ++++++++++++------------ 1 file changed, 12 insertions(+), 12 deletions(-) base-commit: 359c92c02bfae1a6f1e8e37c298e518fd256642c
