SQFS_BLOCK_WRITER_FLAGS

enum SQFS_BLOCK_WRITER_FLAGS

Flags that can be passed to sqfs_block_writer_create.

Enumerator
SQFS_BLOCK_WRITER_HASH_COMPARE_ONLY	If set, only compare checksums when deduplicating blocks. Since squashfs-tools-ng version 1.1, the default for the block writer is to compare checksum & size for blocks during deduplication and then read the potential match back from disk and do a byte for byte comparison to make absolutely sure they match. If this flag is set, the hash & size check is treated as being sufficient for block deduplication, which does increase performance, but risks data loss or corruption if a hash collision occours.
SQFS_BLOCK_WRITER_ALL_FLAGS	A combination of all valid flags.
