Messages in this thread Patch in this message | | | From | Nicolai Stange <> | Subject | [PATCH v6 8/8] debugfs: unproxify files created through debugfs_create_u32_array() | Date | Tue, 22 Mar 2016 14:11:20 +0100 |
| |
The struct file_operations u32_array_fops associated with files created through debugfs_create_u32_array() has been lifetime aware already: everything needed for subsequent operation is copied to a ->f_private buffer at file opening time in u32_array_open(). Now, ->open() is always protected against file removal issues by the debugfs core.
There is no need for the debugfs core to wrap the u32_array_fops with a file lifetime managing proxy.
Make debugfs_create_u32_array() create its files in non-proxying operation mode by means of debugfs_create_file_unsafe().
