Initially the warning was added incorrectly due to unsynchronization of pcs_mds_sys_info structure with the userspace client. Let's sync the structure and fix that. Pavel Butsykin (3): Revert "fs/fuse kio: add warning about jumbo chunks" fs/fuse kio: sync pcs_mds_sys_info struct fs/fuse

[Devel] [PATCH 3/3] fs/fuse kio: add warning about jumbo chunks

KIO doesn't support jumbo chunks yet, so all requests to jumbo chunks are silently redirected to user-space. It will be useful to see a message about this until support has been added to KIO. Signed-off-by: Pavel Butsykin --- fs/fuse/kio/pcs/pcs_fuse_kdirect.c | 3 +++ 1 file changed, 3
