[LTP] [PATCH v2 2/3] lib/tst_device.c: check for BTRFS_SUPER_MAGIC instead of device major of 0

[Jeff Moyer]

Hi, Petr,

Thanks a lot for the review.  I just have one question, below:

SAFE_STATFS appears to be part of the new safe macros
(tst_safe_macros_inline.h), whereas tst_device.c includes the older
macros via #include "safe_macros.h".  How would you like me to proceed?
I could add a SAFE_STATFS to the old macros, or I could submit a prep
patch that converts tst_device to the new macros.  Or something else?

Thanks!
Jeff
