Add process name and pid to locks warning (2022-11-30 05:08:10 -0500)
----------------------------------------------------------------
The main change here is to add the new locks_inode_context helper, and
convert all of the places that dereference inode->i_flctx directly to
use that instead.
There a new helper to indicate whether any locks are held on an inode.
This is mostly for Ceph but may be usable elsewhere too.
Andi Kleen requested that we print the PID when the LOCK_MAND warning
fires, to help track down applications trying to use it.
Finally, we added some new warnings to some of the file locking
functions that fire when the ->fl_file and filp arguments differ. This
helped us find some long-standing bugs in lockd. Patches for those are
in Chuck Lever's tree and should be in his v6.2 PR. After that patch,
people using NFSv2/v3 locking may see some warnings fire until those go
in.
Happy Holidays!
