Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs-2.6
* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs-2.6: quota: Convert quota statistics to generic percpu_counter ext3 uses rb_node = NULL; to zero rb_root. quota: Fixup dquot_transfer reiserfs: Fix resuming of quotas on remount read-write pohmelfs: Remove dead quota code ufs: Remove dead quota code udf: Remove dead quota code quota: rename default quotactl methods to dquot_ quota: explicitly set ->dq_op and ->s_qcop quota: drop remount argument to ->quota_on and ->quota_off quota: move unmount handling into the filesystem quota: kill the vfs_dq_off and vfs_dq_quota_on_remount wrappers quota: move remount handling into the filesystem ocfs2: Fix use after free on remount read-only Fix up conflicts in fs/ext4/super.c and fs/ufs/file.c
