__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")
