From: Nicolai Stange Date: Tue, 22 Mar 2016 13:11:20 +0000 (+0100) Subject: debugfs: unproxify files created through debugfs_create_u32_array() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c4a74f63dfd2e75e7d40a9aaa4052b0ef26e617c;p=linux-beck.git debugfs: unproxify files created through debugfs_create_u32_array() 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().
