| Subject: mark pstore-blk as broken |
| |
| From: Christoph Hellwig <hch@lst.de> |
| |
| [ Upstream commit d07f3b081ee632268786601f55e1334d1f68b997 ] |
| |
| pstore-blk just pokes directly into the pagecache for the block |
| device without going through the file operations for that by faking |
| up it's own file operations that do not match the block device ones. |
| |
| As this breaks the control of the block layer of it's page cache, |
| and even now just works by accident only the best thing is to just |
| disable this driver. |
