2023-04-01libsquashfs: remove the default block writer alignment featureDavid Oberhollenzer
The idea of the block align feature was to allow micro-managing that some files are forcefully aligned to 1k/4k ("device block") boundaries, hoping to improve access time at the cost of data density. The feature was not exposed in the tools for a long time and eventuall added to the sort file. Measurement and experimentation showed, that it in fact worsened the read performance on a test system with an old micro SD card as the bottle neck. The feature is removed, and if needed, can be brought back simply by wrapping/sub-classing the default block writer, if need be..
