[zfs-discuss] [help]Could I have a question that where I can find the core code about COW
I''m reading the source code about ZFS trying to know some details about
COW mechanism.
And I''ve known some related data structures such as dnode_phys_t,
blkptr_t, uberblock_phys_t,objset_phys_t,dnode_t,dmu_buf_impl_t,etc.
but I can''t find the codes about allocating a new block, copying
the modified one to it, and then recursively changing the direckblocks.Where can
I find such codes?
