Here is the deny mode handling overhaul broken out into a separate series, as requested by Christoph. I've tried to address most of his review comments, but I may have missed some. Let me know if if I did. Part of the client_mutex removal series involves cleaning up the handling of deny modes in the server in order to setting and enforcement atomic. This does add a new per-nfs4_file spinlock, but in principle it should never be contended while the client_mutex is still wrapped around all of this code. Jeff Layton (8): nfsd: refactor nfs4_file_get_access and nfs4_file_put_access nfsd: remove nfs4_file_put_fd nfsd: shrink st_access_bmap and st_deny_bmap nfsd: set stateid access and deny bits in nfs4_get_vfs_file nfsd: clean up reset_union_bmap_deny nfsd: always hold the fi_lock when bumping fi_access refcounts nfsd: make deny mode enforcement more efficient and close races in it nfsd: cleanup and rename nfs4_check_open Trond Myklebust (3): nfsd: Add fine grained protection for the nfs4_file->fi_stateids list nfsd: Add locking to the nfs4_file->fi_fds[] array nfsd: clean up helper __release_lock_stateid fs/nfsd/nfs4state.c | 437 ++++++++++++++++++++++++++++++++++++++-------------- fs/nfsd/state.h | 32 +--- 2 files changed, 325 insertions(+), 144 deletions(-) -- 1.9.3 -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
