[PATCH 0/3] CONFIG_VFS_DEBUG at last

From: Mateusz Guzik
Date: Wed Feb 05 2025 - 13:38:59 EST


This adds a super basic version just to get the mechanism going and
adds sample usage.

The macro set is incomplete (e.g., lack of locking macros) and
dump_inode routine fails to dump any state yet, to be implemented(tm).

I think despite the primitive state this is complete enough to start
sprinkling warns as necessary.

Mateusz Guzik (3):
vfs: add initial support for CONFIG_VFS_DEBUG
vfs: catch invalid modes in may_open
vfs: use the new debug macros in inode_set_cached_link()
