From 7b12e49669c99f63bc12351c57e581f1f14d4adf Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 8 Mar 2022 07:05:29 +0100 Subject: fs: remove fs.f_write_hint The value is now completely unused except for reporting it back through the F_GET_FILE_RW_HINT ioctl, so remove the value and the two ioctls for it. Trying to use the F_SET_FILE_RW_HINT and F_GET_FILE_RW_HINT fcntls will now return EINVAL, just like it would on a kernel that never supported this functionality in the first place.
