Hey Linus, /* Summary */ For the v6.13 cycle we switched overlayfs to a variant of override_creds() that doesn't take an extra reference. To this end the {override,revert}_creds_light() helpers were introduced. This series generalizes the idea behind {override,revert}_creds_light() to the {override,revert}_creds() helpers. Afterwards overriding and reverting credentials is reference count free unless the caller explicitly takes a reference. All caller's have been appropriately ported. /* Testing */ gcc version 14.2.0 (Debian 14.2.0-6) Debian clang version 16.0.6 (27+b1) No build failures or warnings were observed. /* Conflicts */ Merge conflicts with mainline ============================= No known conflicts.
