This is a note to let you know that I've just added the patch titled nfsd: NFSD_FILE_KEY_INODE only needs to find GC'ed entries to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: nfsd-nfsd_file_key_inode-only-needs-to-find-gc-ed-en.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit c11b5100eaa42dc4fd6fccaf50aaed30615e4141 Author: Jeff Layton <jlayton@xxxxxxxxxx> Date: Fri Jan 6 10:39:00 2023 -0500 nfsd: NFSD_FILE_KEY_INODE only needs to find GC'ed entries [ Upstream commit 6c31e4c98853a4ba47355ea151b36a77c42b7734 ] Since v4 files are expected to be long-lived, there's little value in closing them out of the cache when there is conflicting access. Change the comparator to also match the gc value in the key. Change both of the current users of that key to set the gc value in the key to "true".
