...tus and ''bytes_deduped'' member. This provides a number of benefits: - We don''t have to fail the entire ioctl because one of the dedupes failed. - Userspace will always know how much progress was made on a file as we always return the number of bytes deduped. #define BTRFS_SAME_DATA_DIFFERS 1 /* For extent-same ioctl */ struct btrfs_ioctl_same_extent_info { __s64 fd; /* in - destination file */ __u64 logical_offset; /* in - start of extent in destination */ __u64 bytes_deduped; /* out - total # of bytes we were able * to dedupe from this file */ /* status of this dedupe oper...
