__kernel_rwf_t was defined with upstream Linux commit ddef7ed2b5cbafae692d1d580bb5a07808926a9c ("annotate RWF_... flags") which has been included in Linux v4.14 and newer. When building xfsprogs against older kernel headers, this type is not defined, leading to the following build error: pwrite.c: In function 'pwrite_f': ../include/xfs/linux.h:236:22: error: '__kernel_rwf_t' undeclared (first use in this function); did you mean '__kernel_off_t'? #define RWF_ATOMIC ((__kernel_rwf_t)0x00000040) ^~~~~~~~~~~~~~ pwrite.c:329:22: note: in expansion of macro 'RWF_ATOMIC' pwritev2_flags |= RWF_ATOMIC; Fixes: ee6c5941352a ("xfs_io: add RWF_ATOMIC support to pwrite") Signed-off-by: Florian Fainelli <florian.fainelli@broadcom.com> --- include/linux.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
