Hi all, At some point, I realized that I've refactored enough of the quota code in XFS that I should evaluate whether or not quota actually works on realtime volumes. It turns out that it nearly works: the only broken pieces are chown and delayed allocation, and reporting of project quotas in the statvfs output for projinherit+rtinherit directories. Fix these things and we can have realtime quotas again after 20 years. If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. With a bit of luck, this should all go splendidly. Comments and questions are, as always, welcome. --D kernel git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git/log/?h=realtime-quotas-6.13 --- Commits in this patchset: * xfs: fix chown with rt quota * xfs: advertise realtime quota support in the xqm stat files * xfs: report realtime block quota limits on realtime directories * xfs: create quota preallocation watermarks for realtime quota * xfs: reserve quota for realtime files correctly * xfs: enable realtime quota again --- fs/xfs/xfs_dquot.c | 37 +++++++++++++----------- fs/xfs/xfs_dquot.h | 18 +++++++++--- fs/xfs/xfs_iomap.c | 37 +++++++++++++++++++----- fs/xfs/xfs_qm.c | 72 ++++++++++++++++++++++++++++++---------------- fs/xfs/xfs_qm_bhv.c | 18 ++++++++---- fs/xfs/xfs_quota.h | 12 ++++---- fs/xfs/xfs_rtalloc.c | 4 ++- fs/xfs/xfs_stats.c | 7 +++- fs/xfs/xfs_super.c | 11 +++---- fs/xfs/xfs_trans.c | 31 +++++++++++++++++++- fs/xfs/xfs_trans_dquot.c | 11 +++++++ 11 files changed, 182 insertions(+), 76 deletions(-)
