Subject: fs/ntfs3: Keep preallocated only if option prealloc enabled
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e95113ed4d428219e3395044e29f5713fc446720;p=linux.git

fs/ntfs3: Keep preallocated only if option prealloc enabled

If size of file was reduced, we still kept allocated blocks.
This commit makes ntfs3 work as other fs like btrfs.

Fixes: 4342306f0f0d ("fs/ntfs3: Add file operations and implementation")
