Subject: [PATCH 1/4] fs/ntfs3: In function ntfs_set_acl_ex do not change inode->i_mode if called from function ntfs_init_acl
Date: Mon, 25 Oct 2021 19:58:26 +0300 [thread overview]
Message-ID: <67d0c9ca-2531-8a8a-ea0b-270dc921e271@paragon-software.com> (raw)
In-Reply-To: <25b9a1b5-7738-7b36-7ead-c8faa7cacc87@paragon-software.com>
ntfs_init_acl sets mode. ntfs_init_acl calls ntfs_set_acl_ex.
ntfs_set_acl_ex must not change this mode.
Fixes xfstest generic/444
Fixes: 83e8f5032e2d ("fs/ntfs3: Add attrib operations")
