The newly added xfs_finish_page_writeback() function causes a harmless gcc warning when debugging is disabled: fs/xfs/xfs_aops.c: In function 'xfs_finish_page_writeback': fs/xfs/xfs_aops.c:97:16: error: unused variable 'blockmask' [-Werror=unused-variable] unsigned int blockmask = (1 << inode->i_blkbits) - 1; ^~~~~~~~~ This adds an #ifdef around the variable declaration to hide it whenever the ASSERT macro is defined as a stub, following the same style as used elsewhere in xfs.
