At the very least you should instead have a single check: if (error) { /* record all the error values */ } else { /* record zeroes */ } Although, I recommend a different approach entirely, and that is to to have /two/ trace points: one for the success case and one for the error case. That way the error case can be enabled persistently, as appropriate, and the success case can be used for general debugging, which ought to be rare once the code is working well and we have good error reporting in user space. In some instances (maybe not here in copy), the success tracepoint is completely unnecessary for everyday operation and can be omitted.

There are 3 more logical decisions after that. (1) dealing with synchronous copy with an incorrect verifier -- perhaps that warrants a separate tracepoints as a generic COPY doesn't capture verifier information at all, (2) deals with completion of async copy but for that we have a tracepoint in the callback, and (3) handling commit after copy but that has a commit tracepoint in the COMMIT operation. > > if (status == -ENOTSUPP) > > dst_server->caps &= ~NFS_CAP_COPY; > > if (status) > > diff --git a/fs/nfs/nfs4trace.h b/fs/nfs/nfs4trace.h > > index ba338ee4a82b..4beb59d78ff3 100644 > > --- a/fs/nfs/nfs4trace.h > > +++ b/fs/nfs/nfs4trace.h > > @@ -2540,6 +2540,107 @@ DECLARE_EVENT_CLASS(nfs4_sparse_event, > > DEFINE_NFS4_SPARSE_EVENT(nfs4_fallocate); > > DEFINE_NFS4_SPARSE_EVENT(nfs4_deallocate); > > > > +TRACE_EVENT(nfs4_copy, > > + TP_PROTO( > > + const struct inode *src_inode, > > + const struct inode *dst_inode, > > + const struct nfs42_copy_args *args, > > + const struct nfs42_copy_res *res, > > + const struct nl4_server *nss, > > + int error > > + ), > > + > > + TP_ARGS(src_inode, dst_inode, args, res, nss, error), > > + > > + TP_STRUCT__entry( > > + __field(unsigned long, error) > > + __field(u32, src_fhandle) > > + __field(u32, src_fileid) > > + __field(u32, dst_fhandle) > > + __field(u32, dst_fileid) > > + __field(dev_t, src_dev) > > + __field(dev_t, dst_dev) > > + __field(int, src_stateid_seq) > > + __field(u32, src_stateid_hash) > > + __field(int, dst_stateid_seq) > > + __field(u32, dst_stateid_hash) > > + __field(loff_t, src_offset) > > + __field(loff_t, dst_offset) > > + __field(bool, sync) > > + __field(loff_t, len) > > + __field(int, res_stateid_seq) > > + __field(u32, res_stateid_hash) > > + __field(loff_t, res_count) > > + __field(bool, res_sync) > > + __field(bool, res_cons) > > + __field(bool, intra) > > + ), > > + > > + TP_fast_assign( > > + const struct nfs_inode *src_nfsi = NFS_I(src_inode); > > + const struct nfs_inode *dst_nfsi = NFS_I(dst_inode); > > + > > + __entry->src_fileid = src_nfsi->fileid; > > + __entry->src_dev = src_inode->i_sb->s_dev; > > + __entry->src_fhandle = nfs_fhandle_hash(args->src_fh); > > + __entry->src_offset = args->src_pos; > > + __entry->dst_fileid = dst_nfsi->fileid; > > + __entry->dst_dev = dst_inode->i_sb->s_dev; > > + __entry->dst_fhandle = nfs_fhandle_hash(args->dst_fh); > > + __entry->dst_offset = args->dst_pos; > > + __entry->len = args->count; > > + __entry->sync = args->sync; > > + __entry->error = error < 0 ? -error : 0; > > + __entry->src_stateid_seq = > > + be32_to_cpu(args->src_stateid.seqid); > > + __entry->src_stateid_hash = > > + nfs_stateid_hash(&args->src_stateid); > > + __entry->dst_stateid_seq = > > + be32_to_cpu(args->dst_stateid.seqid); > > + __entry->dst_stateid_hash = > > + nfs_stateid_hash(&args->dst_stateid); > > + __entry->res_stateid_seq = error < 0 ? 0 : > > + be32_to_cpu(res->write_res.stateid.seqid); > > + __entry->res_stateid_hash = error < 0 ? 0 : > > + nfs_stateid_hash(&res->write_res.stateid); > > + __entry->res_count = error < 0 ? 0 : > > + res->write_res.count; > > + __entry->res_sync = error < 0 ? 0 : > > + res->synchronous; > > + __entry->res_cons = error < 0 ? 0 : > > + res->consecutive; > > + __entry->intra = nss ? 0 : 1; > > + ), > > I have some general comments about the ternaries here > and in some of the other patches. > > At the very least you should instead have a single check: > > if (error) { > /* record all the error values */ > } else { > /* record zeroes */ > } > > Although, I recommend a different approach entirely, > and that is to to have /two/ trace points: one for > the success case and one for the error case.

I think I see what you are saying with having something like (in nfs42proc.c in copy) nfs4_call_sync() if (status) trace_nfs4_copy_err() else trace_nfs4_copy() That would replace my checking for error and setting the field. I can do that. But I'm not sure how to handle sharing of "call" arguments that we'd want to display for both the error case tracepoint and non-error case. If I'm missing an approach on how to can you please share, or otherwise, in my revision I'd re-write using if (error) approach and keep just a single tracepoint. > In some instances (maybe not here in copy), the > success tracepoint is completely unnecessary for > everyday operation and can be omitted. > > What's your thought about that? > > > > + > > + TP_printk( > > + "error=%ld (%s) intra=%d src_fileid=%02x:%02x:%llu " > > + "src_fhandle=0x%08x dst_fileid=%02x:%02x:%llu " > > + "dst_fhandle=0x%08x src_stateid=%d:0x%08x " > > + "dst_stateid=%d:0x%08x src_offset=%llu dst_offset=%llu " > > + "len=%llu sync=%d cb_stateid=%d:0x%08x res_sync=%d " > > + "res_cons=%d res_count=%llu", > > + -__entry->error, > > + show_nfsv4_errors(__entry->error), > > + __entry->intra, > > + MAJOR(__entry->src_dev), MINOR(__entry->src_dev), > > + (unsigned long long)__entry->src_fileid, > > + __entry->src_fhandle, > > + MAJOR(__entry->dst_dev), MINOR(__entry->dst_dev), > > + (unsigned long long)__entry->dst_fileid, > > + __entry->dst_fhandle, > > + __entry->src_stateid_seq, __entry->src_stateid_hash, > > + __entry->dst_stateid_seq, __entry->dst_stateid_hash, > > + __entry->src_offset, > > + __entry->dst_offset, > > + __entry->len, > > + __entry->sync, > > + __entry->res_stateid_seq, __entry->res_stateid_hash, > > + __entry->res_sync, > > + __entry->res_cons, > > + __entry->res_count > > + ) > > +); > > + > > #endif /* CONFIG_NFS_V4_1 */ > > > > #endif /* _TRACE_NFS4_H */ > > -- > > 2.27.0 > > > > -- > Chuck Lever > > > ^ permalink raw reply [flat|nested] 17+ messages in thread

A single error tracepoint is fine with me. If you're curious about multiple tracepoints that record and display the same information, one example is in the fs/nfsd/trace.h file, starting with the NFSD_TRACE_PROC_ARG_FIELDS macro.

It sounds like, if there was already a show_nfs_stable_how() that I could call then I don't need to define what I'm defining? So if I apply your patches and and then my patches on top of that, that seems like the way to go? That depends on if your patch(es) are ready to be submitted or not? Alternatively, your patch(es) can fix my code. I don't have a preference either way. > > > > + > > +TRACE_EVENT(nfs4_cb_offload, > > + TP_PROTO( > > + const struct nfs_fh *cb_fh, > > + const nfs4_stateid *cb_stateid, > > + uint64_t cb_count, > > + int cb_error, > > + int cb_how_stable > > + ), > > + > > + TP_ARGS(cb_fh, cb_stateid, cb_count, cb_error, > > + cb_how_stable), > > + > > + TP_STRUCT__entry( > > + __field(unsigned long, error) > > + __field(u32, fhandle) > > + __field(loff_t, cb_count) > > + __field(int, cb_how) > > + __field(int, cb_stateid_seq) > > + __field(u32, cb_stateid_hash) > > + ), > > + > > + TP_fast_assign( > > + __entry->error = cb_error < 0 ? -cb_error : 0; > > + __entry->fhandle = nfs_fhandle_hash(cb_fh); > > + __entry->cb_stateid_seq = > > + be32_to_cpu(cb_stateid->seqid); > > + __entry->cb_stateid_hash = > > + nfs_stateid_hash(cb_stateid); > > + __entry->cb_count = cb_count; > > + __entry->cb_how = cb_how_stable; > > + ), > > + > > + TP_printk( > > + "error=%ld (%s) fhandle=0x%08x cb_stateid=%d:0x%08x " > > + "cb_count=%llu cb_how=%s", > > + -__entry->error, > > + show_nfsv4_errors(__entry->error), > > + __entry->fhandle, > > + __entry->cb_stateid_seq, __entry->cb_stateid_hash, > > + __entry->cb_count, > > + show_write_mode(__entry->cb_how) > > + ) > > +); > > + > > #endif /* CONFIG_NFS_V4_1 */ > > > > #endif /* _TRACE_NFS4_H */ > > -- > > 2.27.0 > > > > -- > Chuck Lever > > > ^ permalink raw reply [flat|nested] 17+ messages in thread
