commit: 7b32f64bc512b40b268776c5ac4d354b325b3197 ("mm: limit filemap_fault readahead to VMA boundaries")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
[still regression on linux-next/master ec039126b7fac4e3af35ebccaa7c6f9b6875ba81]
testcase: pts
config: x86_64-rhel-9.4
compiler: gcc-14
test machine: 256 threads 2 sockets Intel(R) Xeon(R) 6767P CPU @ 2.4GHz (Granite Rapids) with 256G memory
parameters:
test: svt-av1-2.11.1
option_a: 1
option_b: Bosphorus 4K
cpufreq_governor: performance
