Hello,
kernel test robot noticed a -16.4% regression of filebench.sum_operations/s on:
commit: 6c18ca82c3155bea26e0080ffc613e100b99f706 ("smb: client: force dentry revalidation if nohandlecache is set")
git://git.samba.org/sfrench/cifs-2.6.git for-next-next
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
