| Series | vvfat: Fix write bugs for large files and add iotests | expand |
Explaination of the patch list: These patches fix some bugs found when modifying files in vvfat. First, there was a bug when writing to the cluster 2 or above of a file, it will copy the cluster before it instead, so, when writing to cluster=2, the content of cluster=1 will be copied into disk instead in its place. Another issue was modifying the clusters of a file and adding new clusters, this showed 2 issues: - If the new cluster is not immediately after the last cluster, it will cause issues when reading from this file in the future. - Generally, the usage of info.file.offset was incorrect, and the system would crash on abort() when the file is modified and a new cluster was added. Also, added some iotests for vvfat , covering the this fix and also general behavior such as reading and writing to the first cluster which would pass even before this patch.
