This patchset fixes most of the compiler warnings encountered when building
btrfs with make W=1.
There are two more compiler warnings left in raid56.c:
CC [M] fs/btrfs/raid56.o
fs/btrfs/raid56.c: In function ‘finish_rmw’:
fs/btrfs/raid56.c:1185:6: warning: variable ‘p_stripe’ set but not used [-Wunused-but-set-variable]
int p_stripe = -1;
^
fs/btrfs/raid56.c: In function ‘finish_parity_scrub’:
fs/btrfs/raid56.c:2343:6: warning: variable ‘p_stripe’ set but not used [-Wunused-but-set-variable]
int p_stripe = -1;
^
but I'm currently unsure how an appropriate fix would look like. As far as I
can tell these variables have always been unused since they have been
introduced.
There are still warnings left emitted by kernel-doc but these are subject to
another patchset, this one only addresses the warnings generated by gcc.
Changes to v1:
* Added Reviews
* Dropped already applied patches 4 + 5
* Added EXPORT_FOR_TESTS + users
