This patch allows FILEIO to update hw_max_sectors based on the current max_bytes_per_io. This is required because vfs_[writev,readv]() can accept a maximum of 2048 iovecs per call, so the enforced hw_max_sectors really needs to be calculated based on block_size. This addresses a >= v3.5 bug where block_size=512 was rejecting > 1M sized I/O requests, because FD_MAX_SECTORS was hardcoded to 2048 for the block_size=4096 case. (v2: Use max_bytes_per_io instead of ->update_hw_max_sectors) Reported-by: Henrik Goldman <hg@x-formation.com> Cc: <stable@vger.kernel.org> #3.5+ Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org> |
