*** This bug is a duplicate of bug 2037214 ***
https://bugs.launchpad.net/bugs/2037214
The duplicate status is *clearly wrong*, as #2037214 refers to the
"evict_inodes" issue (now fixed at some point) whereas this bug report
is, according to its title, about the "workqueue:
inode_switch_wbs_work_fn hogged CPU for >10000us 4" issue.
This has not been fixed (I'm seeing it on 6.8.0-31-generic in Noble).
There are solutions posted for it.
