Kernel bug: INFO: trying to register non-static key in ntfs_set_size
Subsystem: ntfs3
Status: fixed

Crash report:
loop0: detected capacity change from 0 to 4096
ntfs3(loop0): Different NTFS sector size (4096) and media sector size (512).
INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe
you didn't initialize this object before use?
turning off the locking correctness validator.
