From cbcf47adc8aadbcaa741391ccfd96f764b50be7e Mon Sep 17 00:00:00 2001 From: Amir Goldstein Date: Wed, 8 Jul 2020 14:11:38 +0300 Subject: [PATCH] fsnotify: return non const from fsnotify_data_inode() Return non const inode pointer from fsnotify_data_inode(). None of the fsnotify hooks pass const inode pointer as data and callers often need to cast to a non const pointer.
