[PATCH next] ntfs: add missing error code in ntfs_mft_record_alloc()
Posted by Dan Carpenter 2 months, 1 week ago
Return -ENOMEM if the kmalloc() fails.  Don't return success.

Fixes: 115380f9a2f9 ("ntfs: update mft operations")

I have wanted to avoid sending patches but it was easier to fix it than
explain the warning.  :P

    fs/ntfs/namei.c:677 __ntfs_create() error: uninitialized symbol 'ni_mrec'.
