If /run/runc and /usr/bin are on different filesystems, overlayfs may enable the xino feature which results in the following log message: kernel: overlayfs: "xino" feature enabled using 3 upper inode bits. Each time we have to protect /proc/self/exe. So disable xino to remove the log message (we don't care about the inode numbers of the files anyway).

If we want to include the docs changes, can you also include #4525? |
Yes, will be in after it is merged. |
Draft
Arguably these docs should live elsewhere (especially if we plan to remove memfd-bind in the future), but for now this is the only place that fully explains this issue.

Backport: #4509 and #4525
In addition to some documentation fixes, fix the
xinodmesg log issue.If /run/runc and /usr/bin are on different filesystems, overlayfs may
enable the xino feature which results in the following log message:
kernel: overlayfs: "xino" feature enabled using 3 upper inode bits.
Each time we have to protect /proc/self/exe. So disable xino to remove
the log message (we don't care about the inode numbers of the files
anyway).
