v2: 1) Prior to calling PipeFS dentry rountines (for both type of clients - SUNPRC and NFS) get the client and drop the list lock instead of replacing per-net locks by mutexes. First two pathes fixes lockdep warnings and next two - dereferencing of released pipe data on eventfd close and in file operations. The following series consists of: --- Stanislav Kinsbursky (4): SUNRPC: release per-net clients lock before calling PipeFS dentries creation NFS: release per-net clients lock before calling PipeFS dentries creation SUNRPC: check RPC inode's pipe reference before dereferencing SUNRPC: move waitq from RPC pipe to RPC inode fs/nfs/client.c | 2 + fs/nfs/idmap.c | 8 +++- include/linux/sunrpc/rpc_pipe_fs.h | 2 + net/sunrpc/clnt.c | 10 ++++- net/sunrpc/rpc_pipe.c | 71 +++++++++++++++++++++++------------- 5 files changed, 60 insertions(+), 33 deletions(-) -- 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
