[Bug 2084384] [NEW] CONFIG_READ_ONLY_THP_FOR_FS is not set

Public bug reported:

CONFIG_READ_ONLY_THP_FOR_FS allows transparent hugepages to apply to
.text segments of executables (if they execute the appropriate madvise()
call), leading to better performance.

Unfortunately, it is not enabled in Ubuntu. Please enable it.

# grep CONFIG_READ_ONLY_THP_FOR_FS /boot/config-6.11.0-8-generic
