[PATCH 4/5] ntfs: propagate the map_mft_record() error in ntfs_attrlist_entry_add()

[Baolin Liu]

From: Baolin Liu <liubaolin@xxxxxxxxxx>

ntfs_attrlist_entry_add() replaces the map_mft_record() error with -EIO,
so an -ENOMEM allocation failure is reported as an I/O error. Both
callers pass the value on to ntfs_attr_add(), which no longer collapses
it since commit 8efe00b098b5 ("ntfs: preserve error code in
ntfs_resident_attr_record_add()").

Return PTR_ERR(ni_mrec) instead. Also fix the debug message.

Fixes: 495e90fa3348 ("ntfs: update attrib operations")
