From 8ca577223f75230a746a06f4566c53943f78d5d0 Mon Sep 17 00:00:00 2001 From: Fabian Frederick Date: Mon, 7 Apr 2014 15:39:01 -0700 Subject: affs: add mount option to avoid filename truncates Normal behavior for filenames exceeding specific filesystem limits is to refuse operation. AFFS standard name length being only 30 characters against 255 for usual Linux filesystems, original implementation does filename truncate by default with a define value AFFS_NO_TRUNCATE which can be enabled but needs module compilation. This patch adds 'nofilenametruncate' mount option so that user can easily activate that feature and avoid a lot of problems (eg overwrite files ...)
