NFS: Fix inheritance of the block sizes when automounting

2025-11-29T22:23:03+00:00

Only inherit the block sizes that were actually specified as mount parameters for the parent mount. Fixes: 62a55d088cd8 ("NFS: Additional refactoring for fs_context conversion") Signed-off-by: Trond Myklebust

NFS: Request a directory delegation on ACCESS, CREATE, and UNLINK

2025-11-23T21:01:47+00:00

This patch adds a new flag: NFS_INO_REQ_DIR_DELEG to signal that a directory wants to request a directory delegation the next time it does a GETATTR. I have the client request a directory delegation when doing an access, create, or unlink call since these calls indicate that a user is working with a directory.

NFS: use a hash table for delegation lookup

2025-07-22T12:10:41+00:00

nfs_delegation_find_inode currently has to walk the entire list of delegations per inode, which can become pretty large, and can become even larger when increasing the delegation watermark. Add a hash table to speed up the delegation lookup, sized as a fraction of the delegation watermark.

NFS: track active delegations per-server

2025-07-22T12:10:41+00:00

The active delegation watermark was added to avoid overloading servers. Track the active delegation per-server instead of globally so that clients talking to multiple servers aren't limited by the global limit.

NFS: remove unused pnfs_ld_data field from struct nfs_server

NFS: Add support for fallocate(FALLOC_FL_ZERO_RANGE)

2025-05-28T21:17:13+00:00

This implements a suggestion from Trond that we can mimic FALLOC_FL_ZERO_RANGE by sending a compound that first does a DEALLOCATE to punch a hole in a file, and then an ALLOCATE to fill the hole with zeroes. There might technically be a race here, but once the DEALLOCATE finishes any reads from the region would return zeroes anyway, so I don't expect it to cause problems. Signed-off-by: Anna Schumaker
