linux-toradex.git/fs/logfs/super.c, branch v3.0.7 Linux kernel for Apalis and Colibri modules logfs: initialize superblock entries earlier 2011-05-03T23:10:25+00:00 Linus Torvalds torvalds@linux-foundation.org 2011-05-03T23:10:25+00:00 cce2c56e7666199916525907dc817209dd58287c In particular, s_freeing_list needs to be initialized early, since it is used on some of the error paths when mounts fail. The mapping inode, for example, would be initialized and then free'd on an error path before s_freeing_list was initialized, but the inode drop operation needs the s_freeing_list to be set up. Normally you'd never see this, because not only is logfs fairly rare, but a successful mount will never have any issues.
