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 Johannes Thumshirn (5): btrfs: remove unused drop_on_err in btrfs_mkdir() btrfs: remove set but not used variable err in btrfs_add_link btrfs: remove unused function btrfs_sysfs_feature_update() btrfs: introduce EXPORT_FOR_TESTS macro btrfs: use EXPORT_FOR_TESTS for conditionally shared functions fs/btrfs/ctree.h | 6 ++++++ fs/btrfs/extent_io.c | 14 ++------------ fs/btrfs/extent_io.h | 7 +++---- fs/btrfs/free-space-tree.c | 8 ++++++-- fs/btrfs/inode.c | 16 ++++++---------- fs/btrfs/sysfs.c | 33 --------------------------------- fs/btrfs/sysfs.h | 2 -- fs/btrfs/tests/extent-io-tests.c | 10 +++++----- 8 files changed, 28 insertions(+), 68 deletions(-)
