From 18e39fb960e6a908ac5230b57e3d0d6c25232368 Mon Sep 17 00:00:00 2001 From: Namjae Jeon Date: Sun, 19 Jun 2022 22:35:48 +0900 Subject: [PATCH] ksmbd: set the range of bytes to zero without extending file size in FSCTL_ZERO_DATA 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.
