From: Chuck Lever <chuck.lever@xxxxxxxxxx> These needed enough cosmetic changes that a v4 posting is warranted. Some of these could add a few more arguments, but the basic infrastructure is solid enough to run with. Changes in v4: - Replace usage of __array/memcpy for capturing sockaddrs - Add NFSD_TRACE_PROC_CALL macros instead of re-using SVC_RQST_ENDPOINT - Const-ify tracepoint pointer arguments - Rename nfsd_setattr and nfsd_lookup_dentry tracepoints to include _vfs_ - Restructure the new READDIR tracepoint to capture the "count" argument - Add non-empty patch descriptions to silence checkpatch.pl - Link to v3: https://lore.kernel.org/r/20250503-nfsd-tracepoints-v3-0-d89f445969af@xxxxxxxxxx Changes in v3: - move most of the tracepoints into non-version specific nfsd/vfs.c calls - rename them with a nfsd_vfs_* prefix - remove the dprintks in separate patches - Link to v2: https://lore.kernel.org/r/20250409-nfsd-tracepoints-v2-0-cf4e084fdd9c@xxxxxxxxxx Changes in v2: - Break tracepoints out into multiple patches - Flesh out the tracepoints in these locations to display the same info as legacy dprintks. - have all the tracepoints SVC_XPRT_ENDPOINT_* info - update svc_xprt_dequeue tracepoint to show how long xprt was on queue - Link to v1: https://lore.kernel.org/r/20250306-nfsd-tracepoints-v1-0-4405bf41b95f@xxxxxxxxxx Chuck Lever (2): NFSD: Use sockaddr instead of a generic array NFSD: Add a Call equivalent to the NFSD_TRACE_PROC_RES macros Jeff Layton (16): nfsd: add a tracepoint for nfsd_setattr nfsd: add a tracepoint to nfsd_lookup_dentry nfsd: add nfsd_vfs_create tracepoints nfsd: add tracepoint to nfsd_symlink nfsd: add tracepoint to nfsd_link() nfsd: add tracepoints for unlink events nfsd: add tracepoint to nfsd_rename nfsd: add tracepoint to nfsd_readdir nfsd: add tracepoint for getattr and statfs events nfsd: remove old v2/3 create path dprintks nfsd: remove old v2/3 SYMLINK dprintks nfsd: remove old LINK dprintks nfsd: remove REMOVE/RMDIR dprintks nfsd: remove dprintks for v2/3 RENAME events nfsd: remove legacy READDIR dprintks nfsd: remove legacy dprintks from GETATTR and STATFS codepaths fs/nfsd/nfs3proc.c | 63 +-------- fs/nfsd/nfs4proc.c | 5 + fs/nfsd/nfsproc.c | 35 +---- fs/nfsd/trace.h | 300 ++++++++++++++++++++++++++++++++++++++-- fs/nfsd/vfs.c | 16 ++- include/trace/misc/fs.h | 21 +++ 6 files changed, 336 insertions(+), 104 deletions(-) -- 2.49.0
