Series | Introduce mtdblock device | expand |
Hi Alexey, The CI still detects some errors when applying both series: - Introduce mtdblock device - Introduce UBI block device As an example: +/opt/gcc-13.2.0-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/13.2.0/../../../../arm-linux-gnueabi/bin/ld: /tmp/ccOTHlvl.ltrans4.ltrans.o: in function `mtd_blk_read': 6816+drivers/mtd/mtdblock.c:95:(.text.mtd_blk_read+0x40): undefined reference to `mtd_read' 6817+/opt/gcc-13.2.0-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/13.2.0/../../../../arm-linux-gnueabi/bin/ld: /tmp/ccOTHlvl.ltrans4.ltrans.o: in function `mtd_blk_write': 6818+drivers/mtd/mtdblock.c:162:(.text.mtd_blk_write+0x9a): undefined reference to `mtd_read' 6819+/opt/gcc-13.2.0-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/13.2.0/../../../../arm-linux-gnueabi/bin/ld: drivers/mtd/mtdblock.c:122:(.text.mtd_blk_write+0xf4): undefined reference to `mtd_erase' 6820+/opt/gcc-13.2.0-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/13.2.0/../../../../arm-linux-gnueabi/bin/ld: /tmp/ccOTHlvl.ltrans4.ltrans.o:drivers/mtd/mtdblock.c:126:(.text.mtd_blk_write+0x110): undefined reference to `mtd_write' 6821+collect2: error: ld returned 1 exit status 6822+/opt/gcc-13.2.0-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/13.2.0/../../../../arm-linux-gnueabi/bin/ld: /tmp/ccaNKMBK.ltrans2.ltrans.o: in function `mtd_blk_read': 6823+drivers/mtd/mtdblock.c:95:(.text.mtd_blk_read+0x36): undefined reference to `mtd_read' 6824+/opt/gcc-13.2.0-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/13.2.0/../../../../arm-linux-gnueabi/bin/ld: /tmp/ccaNKMBK.ltrans2.ltrans.o: in function `mtd_blk_write': 6825+drivers/mtd/mtdblock.c:162:(.text.mtd_blk_write+0x88): undefined reference to `mtd_read' 6826+/opt/gcc-13.2.0-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/13.2.0/../../../../arm-linux-gnueabi/bin/ld: drivers/mtd/mtdblock.c:122:(.text.mtd_blk_write+0xe0): undefined reference to `mtd_erase' 6827+/opt/gcc-13.2.0-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/13.2.0/../../../../arm-linux-gnueabi/bin/ld: /tmp/ccaNKMBK.ltrans2.ltrans.o:drivers/mtd/mtdblock. Furthermore, I need to fix something in applying the patches. So, please rebase your series on master and run the tests locally: Please read tools/buildman/buildman.rst and .gitlab-ci.yml to get info.
