Zdenek Kabelac	ca74ba6f16	device_mapper: slight improvement of tok_match Reduce amount of unnecessary instructions for some code paths.	2024-10-14 11:31:40 -05:00
Zdenek Kabelac	7b6a800e4f	import_vsn1: increate hash size With larger amount of LV hashing buckets within VG, until better structures for dynamic handling of LV elements will be used.	2024-10-14 11:31:40 -05:00
Zdenek Kabelac	c22ed72e7d	device_mapper: slight reorder for _get_token For most common part check for '#' when it's known it's not a space. And also when we checked for '\n' we dont need to check again isspace().	2024-10-14 11:31:40 -05:00
Zdenek Kabelac	faf5fddbec	device_mapper: nodes and values with strings Avoid double pool allocation call by placing string directly after the node/value structure end. It would be likely better to not copy the string at all and derefence it from the original string however that is much larger rework - and also for unescaping we would need to allocate anyway.	2024-10-14 11:31:40 -05:00
Zdenek Kabelac	f4dc2b9aa3	crc: add newer zlib code This code is faster when calculating crc32 checksum for larger block areas. There is also SIMD variant present in the code, however ATM the influence on performance of lvm2 is not that big..	2024-10-14 11:31:40 -05:00
Zdenek Kabelac	6de4590cf9	crc: move static table Move static table upward in the code so it can be shared with another 'crc' implementation.	2024-10-14 11:31:40 -05:00
David Teigland	8bfbb623d7	config: set vg_copy_internal to binary for testing	2024-10-14 11:31:40 -05:00
David Teigland	77305127e4	vg: use vg_copy_struct in second location	2024-10-14 11:31:40 -05:00
