hi, we reported "[kdave-btrfs-devel:dev/guilherme/temp-fsid-v4] [btrfs] 6c9131ed0d: stress-ng.sync-file.ops_per_sec -44.2% regression" in https://lore.kernel.org/all/202309261552.a03eeb4c-oliver.sang@xxxxxxxxx/ when this commit is: commit: 6c9131ed0d644324adeeaccd2feeef8d04950b2d ("btrfs: always reserve space for delayed refs when starting transaction") https://github.com/kdave/btrfs-devel.git dev/guilherme/temp-fsid-v4 we also noticed from https://lore.kernel.org/all/20230927174741.GB13697@xxxxxxxxxxxxx/ the decision is to keep this patch, the performance issue will be addressed later. now this commit is in linux-next/master, we captured the regression from fxmark tests. below fomal report FYI. Hello, kernel test robot noticed a -90.4% regression of fxmark.ssd_btrfs_MWUM_72_bufferedio.works/sec on: commit: 28270e25c69a2c76ea1ed0922095bffb9b9a4f98 ("btrfs: always reserve space for delayed
