Tarkan, thank you for your advise.Ok then. Good luck at your merging into mainline.
Actually I broke functions and files into small pieces. Additionally I
applied CONFIG_AUFS_* conditions in fs/aufs/Makefile. When you review
aufs source files, I'd suggest you to read in this order.
aufs-y := module.o sbinfo.o super.o branch.o xino.o sysaufs.o opts.o \
wkq.o vfsub.o dcsub.o \
cpup.o whout.o plink.o wbr_policy.o \
dinfo.o dentry.o \
finfo.o file.o f_op.o \
dir.o vdir.o \
iinfo.o inode.o i_op.o i_op_add.o i_op_del.o i_op_ren.o \
ioctl.o
aufs-$(CONFIG_SYSFS) += sysfs.o
aufs-$(CONFIG_AUFS_BDEV_LOOP) += loop.o
aufs-$(CONFIG_AUFS_HINOTIFY) += hinotify.o
aufs-$(CONFIG_AUFS_DEBUG) += debug.o
aufs-$(CONFIG_AUFS_MAGIC_SYSRQ) += sysrq.o
If I am still misunderstanding, please let me know.
