[PATCH] fs/ntfs3: drop preallocated clusters for sparse and compressed files

Posted by Konstantin Komarov 1 month, 2 weeks ago

Do not keep preallocated clusters for sparsed and compressed files.
Preserving preallocation in these cases causes fsx failures when running
with sparse files and preallocation enabled.
