[LU-11545] debugfs: "ncheck -c" does not work correctly

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Affects Version/s: Lustre 2.12.0
• Labels: e2fsprogs
• Severity: 3

Description

I noticed when investigating LU-11446 that debugfs is unhappy about the file type stored in the directory (verified if the "-c" option is used):

debugfs -c /dev/loop0
debugfs 1.44.3.wc1
debugfs: ncheck -c 164
Inode   Pathname
164     /REMOTE_PARENT_DIR/0x200000204:0x1:0x0   <--- BAD FILETYPE
debugfs: ls -l /REMOTE_PARENT_DIR
:
:
    164  100644 (17)      0      0       0 

However, it appears the same problem is true for other directories, so it is not an issue with REMOTE_PARENT_DIR. I suspect it is instead a problem that ncheck -c is not masking off the dirdata flags from the filetype.

Also, it looks like the usage message for "ls" is not including the "-D" option to print the dirdata fields.
