UDF and quota changes for 4.6-rc1

Hello Linus,

could you please pull from

git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs.git for_linus

This pull request contains rewrite of UDF handling of filename encoding to fix remaining overflow issues from Andrew Gabbasov and quota changes to support new Q_[X]GETNEXTQUOTA quotactl for VFS quota formats.

The pull also contains XFS changes for Q_[X]GETNEXTQUOTA support since I have pulled a branch from Dave Chinner's tree and based support for VFS quota formats on that. I have verified that the same branch is included in Dave's pull request to you so things should work out without issues.

Top of the tree is ab73ef46398e. The full shortlog is:

Andrew Gabbasov (5):
udf: Parameterize output length in udf_put_filename
udf: Join functions for UTF8 and NLS conversions
udf: Adjust UDF_NAME_LEN to better reflect actual restrictions
udf: Remove struct ustr as non-needed intermediate storage
udf: Merge linux specific translation into CS0 conversion function

Carlos Maiolino (1):
xfs: Split default quota limits by quota type

Eric Sandeen (9):
quota: remove unused cmd argument from quota_quotaon()
quota: add new quotactl Q_XGETNEXTQUOTA
quota: add new quotactl Q_GETNEXTQUOTA
xfs: don't overflow quota ID when initializing dqblk
xfs: get quota inode from mp & flags rather than dqp
xfs: Factor xfs_seek_hole_data into helper
xfs: wire up Q_XGETNEXTQUOTA / get_nextdqblk
quota: Fixup comments about return value of Q_[X]GETNEXTQUOTA
ext4: Make Q_GETNEXTQUOTA work for quota in hidden inodes

Jan Kara (8):
Merge branch 'xfs-get-next-dquot-4.6' of git://git.kernel.org/.../dgc/linux-xfs into for_next
quota: Allow Q_GETQUOTA for frozen filesystem
udf: Use separate buffer for copying split names
quota: Add support for ->get_nextdqblk() for VFS quota
quota_v2: Implement get_next_id() for V2 quota format
ocfs2: Implement get_next_id()
quota: Fix possible races during quota loading
quota: Forbid Q_GETQUOTA and Q_GETNEXTQUOTA for frozen filesystem

Nikolay Borisov (1):
