| | | | | | | | | | | | | | | | | | list_entry is just a wrapper for container_of, but it is arguably wrong (and slightly confusing) to use it when the pointed-to struct member is not a struct list_head.

* affs: add mount option to avoid filename truncatesFabian Frederick2014-04-074-30/+51
| | | | | | | | | | | | | | | | | | 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 ...)

| | | | | | | | | | | | | Commit 0edf977d2ae3 ("[readdir] convert affs") returns directly -EIO without unlocking dir inode and releasing dir bh when second affs_bread sequence fails. This patch restores initial behaviour. It also fixes pr_debug and affs_error to fit in 80 columns + removes reference to filldir (replaced by dir_emit in the commit above).
