| Subject: fuse: fix mknod of regular file |
| |
| From: Miklos Szeredi <mszeredi@suse.cz> |
| |
| The wrong lookup flag was tested in ->create() causing havoc (error or |
| Oops) when a regular file was created with mknod() in a fuse |
| filesystem. |
| |
| Thanks to J. Cameijo Cerdeira for the report. |
| |
| Kernels 2.6.18 onward are affected. Please apply to -stable as well. |
