Subject: [PATCH 19/21] erofs: kill all erofs specific fault injection
Date: Sun,  1 Sep 2019 13:51:28 +0800
Message-ID: <20190901055130.30572-20-hsiangkao@aol.com> (raw)
In-Reply-To: <20190901055130.30572-1-hsiangkao@aol.com>

From: Gao Xiang <gaoxiang25@huawei.com>

As Christoph suggested [1], "Please just use plain kmalloc
everywhere and let the normal kernel error injection code
take care of injeting any errors."

 =============
 
-fault_injection=%d     Enable fault injection in all supported types with
-                       specified injection rate. Supported injection type:
-                       Type_Name                Type_Value

 (no)user_xattr         Setup Extended User Attributes. Note: xattr is enabled
                        by default if CONFIG_EROFS_FS_XATTR is selected.
 (no)acl                Setup POSIX Access Control List. Note: acl is enabled
