Summary: XFS support for dt_type in readdir results
Product: File System
Version: 2.5
KernelVersion: 2.6.28.4
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: enhancement
Priority: P1
Component: XFS
AssignedTo: xfs-masters@xxxxxxxxxxx
ReportedBy: edwintorok@xxxxxxxxx
XFS doesn't support the dt_type member in readdir results, it fills it with
DT_UNKNOWN.
These are the filesystems that appear to support the dt_type field:
9p, btrfs, cifs, coda, ext2, ext3, ext4, fat, hfs, hfsplus, jffs2, ntfs, ocfs2,
omfs, openpromfs, romfs, squashfs, ubifs, ufs
I would like XFS to support it as well, is there something in XFS's design that
prevents it, or was it just not implemented?
It would be useful, because you can skip stat()-ing files, and can traverse
directories faster by just looking at the ->dt_type field to know if it is a
file/directory/something else.
