| Subject: vfs: add "device" tag to /proc/self/mountstats |
| |
| From: Bryan Schumaker <bjschuma@netapp.com> |
| |
| commit a877ee03ac010ded434b77f7831f43cbb1fcc60f upstream. |
| |
| nfsiostat was failing to find mounted filesystems on kernels after |
| 2.6.38 because of changes to show_vfsstat() by commit |
| c7f404b40a3665d9f4e9a927cc5c1ee0479ed8f9. This patch adds back the |
| "device" tag before the nfs server entry so scripts can parse the |
| mountstats file correctly. |
