Currently, when fdset_new_fill() fails to open /proc/self/fd or
encounters an error while processing individual file descriptors
(such as fcntl or fstat failures), it returns a silent error code.
For debugging rarely reproducible failures it becomes difficult to
know the exact cause of failure
This commit updates the function to use log_debug_errno() for all
error paths and hence provides better visibility into why FD collection
failed, including the path of the problematic FD (via fd_get_path)
and its inode type.

Hi Team,
Any input on this patch
I have backported this patch which i have merged in systemd upstream code base
I could not see this patch in master-next branch of openembedded-core - OpenEmbedded Core layer ( https://git.openembedded.org/openembedded-core/log/?h=master-next )
Hence wanted to check if there is any feedback from team
Thanks .
Ashish

Hi Team,
As suggested earlier , have already rebased to latest systemd code base
Does team have any suggestion on https://lists.openembedded.org/g/openembedded-core/message/232763
I still don't see in master-next branch
Thanks ,

Hello,
This is the second version of this patch. Please see [0] for how to mark
it as such and handle patches iterations (Note the patch changelog below
the "---" line). This will make the reviews a lot easier and less
confusing for reviewers.

This changes the systemd recipe, so the commit subject prefix should
be "systemd:", e.g.:
systemd: Add detailed debug logging to fdset_new_fill()
