1. test_bit was used to return true boolean value, if BIO_UPTODATE bit of bio->bi_flags is set. But the same job can be done by checking bio->bi_error, implemented in linux kernel 4.3 and above. If bio->bi_error is set, then it denotes error. Ref:4246a0b63bIt solves below build error: -- snip -- iscsitarget-1.4.20.3+svn502/kernel/block-io.c:40:19: error: 'BIO_UPTODATE' undeclared (first use in this function) error = test_bit(BIO_UPTODATE, &bio->bi_flags) ? error : -EIO; -- CUT -- 2. bio can always be filled to a maximum value of BIO_MAX_PAGES, so no need to check for min value for linux kernel 4.3 and above. Ref:b54ffb73caIt solves below build error: -- snip -- iscsitarget-1.4.20.3+svn502/kernel/block-io.c:80:15: error: implicit declaration of function 'bio_get_nr_vecs' [-Werror=implicit-function-declaration] max_pages = bio_get_nr_vecs(bio_data->bdev); -- CUT -- 3. Remove unwanted explicit setting of CFLAGS and CC flags. Setting them in oe_runmake command, will override CFLAGS mentioned in iscsitarget Makefile and resulting in a below error: -- snip -- In file included from iscsid.c:38:0: iscsid.h:38:19: fatal error: iet_u.h: No such file or directory compilation terminated. In file included from conn.c:15:0: iscsid.h:38:19: fatal error: iet_u.h: No such file or directory compilation terminated. -- CUT -- Signed-off-by: Jagadeesh Krishnanjanappa <jkrishnanjanappa@mvista.com> Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com> Signed-off-by: Joe MacDonald <joe_macdonald@mentor.com>
