Miklos, This is a resend of the patches that teach fs/fuse/ to give filesystems full control over data cache if the filesystem server indicates to kernel that it is fully responsible for data cache invalidation. This functionality is essential when the data in cache are relatively big and it is very desirable to avoid automatically clearing the data cache of inode on file size change. The second patch of the series describes the problem in details as well as the fix to it. I send the change initially ~ 2 weeks ago https://lwn.net/ml/linux-fsdevel/20190315212556.9315-1-kirr@xxxxxxxxxx/ but had not heard from you at all. Could you please have a look?
