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: https://github.com/torvalds/linux/commit/4246a0b63bd8f56a1469b12eafeb875b1041a451
It 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: https://github.com/torvalds/linux/commit/b54ffb73cadcdcff9cc1ae0e11f502407e3e2e4c
It 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:

compilation terminated.

The element skc_v6_daddr (in struct sock_common) is defined in
kernel source only when CONFIG_IPV6 is enabled. Hence, access
sk_v6_daddr element (i.e __sk_common.skc_v6_daddr) only when CONFIG_IPV6
is defined; to fix below error in world build:
-- snip --
