Subject: ksmbd: set the range of bytes to zero without extending file size in FSCTL_ZERO_DATA
From: Namjae Jeon <linkinjeon@xxxxxxxxxx>
commit 18e39fb960e6a908ac5230b57e3d0d6c25232368 upstream.
generic/091, 263 test failed since commit f66f8b94e7f2 ("cifs: when
extending a file with falloc we should make files not-sparse").
FSCTL_ZERO_DATA sets the range of bytes to zero without extending file
size. The VFS_FALLOCATE_FL_KEEP_SIZE flag should be used even on
non-sparse files.
