Hello,
kernel test robot noticed a -5.8% regression of filebench.sum_operations/s on:
commit: 55c7788c37242702868bfac7861cdf0c358d6c3d ("smb: client: set correct d_type for reparse points under DFS mounts")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: filebench
test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz (Ice Lake) with 128G memory
parameters:
disk: 1HDD
fs: xfs
fs2: cifs
test: listdirs.f
cpufreq_governor: performance

the same patch/commit), kindly add following tags
