| * Fix JFFS2 sync silent failureJörn Engel2010-04-221-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | JFFS2 does not appear to set s_bdi anywhere. And as of 32a88aa1, __sync_filesystem() will return 0 if s_bdi is not set. As a result, sync_fs() is never called for jffs2 and whatever remains in the wbuf will not make it to the device. Fix that up by assigning the mtd bdi.

* vfs: simple_set_mnt() should return voidSukadev Bhattiprolu2009-03-271-2/+5
| | | | | | | | | | | | | | | | | | | | | | | simple_set_mnt() is defined as returning 'int' but always returns 0. Callers assume simple_set_mnt() never fails and don't properly cleanup if it were to _ever_ fail. For instance, get_sb_single() and get_sb_nodev() should: up_write(sb->s_unmount); deactivate_super(sb); if simple_set_mnt() fails. Since simple_set_mnt() never fails, would be cleaner if it did not return anything.

* Embed a struct path into struct nameidata instead of nd->{dentry,mnt}Jan Blunck2008-02-141-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the central patch of a cleanup series. In most cases there is no good reason why someone would want to use a dentry for itself. This series reflects that fact and embeds a struct path into nameidata. Together with the other patches of this series - it enforced the correct order of getting/releasing the reference count on <dentry,vfsmount> pairs - it prepares the VFS for stacking support since it is essential to have a struct path in every place where the stack can be traversed - it reduces the overall code size: without patch series: text data bss dec hex filename 5321639 858418 715768 6895825 6938d1 vmlinux with patch series: text data bss dec hex filename 5320026 858418 715768 6894212 693284 vmlinux This patch: Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.
