  SUNRPC: fix gss_auth kref leak in gss_alloc_msg error path (2026-02-09 16:39:50 -0500)

----------------------------------------------------------------
NFS Client Updates for Linux 7.0

New Features:
 * Use an LRU list for returning unused delegations
 * Introduce a KConfig option to disable NFS v4.0 and make NFS v4.1 the default

Bugfixes:
 * NFS/localio: Handle short writes by retrying
 * NFS/localio: prevent direct reclaim recursion into NFS via nfs_writepages
 * NFS/localio: use GFP_NOIO and non-memreclaim workqueue in nfs_local_commit
 * NFS/localio: remove -EAGAIN handling in nfs_local_doio()
 * pNFS: fix a missing wake up while waiting on NFS_LAYOUT_DRAIN
 * fs/nfs: Fix a readdir slow-start regression
 * SUNRPC: fix gss_auth kref leak in gss_alloc_msg error path

Other Cleanups and Improvements:
  * A few other NFS/localio cleanups
  * Various other delegation handling cleanups from Christoph
  * Unify security_inode_listsecurity() calls
  * Improvements to NFSv4 lease handling
  * Clean up SUNRPC *_debug fields when CONFIG_SUNRPC_DEBUG is not set

Thanks,
Anna
