Description Carol Soto 2024-01-29 19:22:52 UTC

If using 64K kernel and doing tail to sysfs is not working. 
There is a patch to coreutils that will resolve this issue

https://github.com/coreutils/coreutils/commit/73d119f4f

Here is an example when doing tail with 64k page

/root/coreutils/src # uname -a
Linux XXXX 5.14.21-150500.55.28-64kb #1 SMP PREEMPT_DYNAMIC Fri Sep 22 10:04:29 UTC 2023 (c11336f) aarch64 aarch64 aarch64 GNU/Linux
/root/coreutils/src # rpm -qa | grep coreutils
coreutils-lang-8.32-150400.7.5.noarch
coreutils-8.32-150400.7.5.aarch64

/root/coreutils/src # tail /sys/kernel/mm/transparent_hugepage/defrag
/root/coreutils/src # tail /sys/kernel/mm/transparent_hugepage/enabled 
/root/coreutils/src # 


If build coreutils with the patch
/root/coreutils/src # ./tail /sys/kernel/mm/transparent_hugepage/defrag
always defer defer+madvise [madvise] never
/root/coreutils/src # ./tail /sys/kernel/mm/transparent_hugepage/enabled
[always] madvise never

Thanks for the report, I've already backported commit 73d119f4f to SLE15-SP5 coreutils, and submitted it to maintenance. It is currently only pending package maintainer review.

If you require a coreutils package PTF you'll need to raise an L3 request, otherwise the fix will be released in the next update.

Thanks, I am probably ok for the next update. What is the ETA for the next update? 

Thanks,
Carol

I cannot say since it is still pending acceptance review, and after that it depends on the QA/maintenance pipeline. I believe that our maintenance can provide an estimate once it gets accepted.

The planned release date according to our Maintenance is expected to be at 2024-03-11.

I am resolving the ticket as fixed, but if you need it sooner (via PTF) please do reopen this ticket along with a support request, and L3 will take care of it.

Quick question is this fix available?

I don't see it as released yet.

@Olivier can you please comment on this (since I do not have much visibility into the maintenance/release process). Something seems to be delaying the release.

Comment 11 Olivier Tilloy 2024-03-19 05:39:04 UTC

The fix had been pending a QA review for quite some time, which is now done. I have requested the publication, which should be happening within minutes.
