tests: extend test 131 to cover availability of the write-zeroes (2023-09-20
10:14:15 +0200)
----------------------------------------------------------------
Parallels format driver:
* regular calculation of cluster used bitmap of the image file
* cluster allocation on the base of that bitmap (effectively allocation of
new clusters could be done inside the image if that offset space is unused)
* support of DISCARD and WRITE_ZEROES operations
* image check bugfixes
* unit tests fixes
* unit tests covering new functionality
----------------------------------------------------------------
Denis V. Lunev (22):
parallels: fix formatting in bdrv_parallels initialization
parallels: mark driver as supporting CBT
parallels: fix memory leak in parallels_open()
parallels: invent parallels_opts_prealloc() helper to parse prealloc opts
parallels: return earler in fail_format branch in parallels_open()
parallels: return earlier from parallels_open() function on error
parallels: refactor path when we need to re-check image in parallels_open
parallels: create mark_used() helper which sets bit in used bitmap
tests: ensure that image validation will not cure the corruption
parallels: fix broken parallels_check_data_off()
parallels: add test which will validate data_off fixes through repair
parallels: collect bitmap of used clusters at open
tests: fix broken deduplication check in parallels format test
tests: test self-cure of parallels image with duplicated clusters
parallels: accept multiple clusters in mark_used()
parallels: update used bitmap in allocate_cluster
parallels: naive implementation of allocate_clusters with used bitmap
parallels: improve readability of allocate_clusters
parallels: naive implementation of parallels_co_pdiscard
tests: extend test 131 to cover availability of the discard operation
parallels: naive implementation of parallels_co_pwrite_zeroes
tests: extend test 131 to cover availability of the write-zeroes
