Hi all, This series replaces q_core (the ondisk quota structure) in the incore dquot structure with a quota resource control structure containing the count, reservation, limits, timers, and warnings. Each dquot gets three of these resource control structures (blocks, inodes, rt blocks). Doing this enables us to remove a whole lot of noisy endian conversions in the quota code, and enables us to refactor a bunch of open-coded logic to pass around pointers to quota resource control structs. Note that these cleanups are a prerequisite for the bigtime patchset, as it depends on incore quota timers being time64_t to take advantage of the 64-bit time functions in the kernel with fewer places to trip over the ondisk format. If you're going to start using this mess, you probably ought to just pull from my git trees, which are linked below. This is an extraordinary way to destroy everything. Enjoy! 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=remove-quota-qcore xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=remove-quota-qcore --- fs/xfs/libxfs/xfs_quota_defs.h | 2 fs/xfs/scrub/quota.c | 69 +++----- fs/xfs/xfs_dquot.c | 283 +++++++++++++++++++--------------- fs/xfs/xfs_dquot.h | 54 +++++-- fs/xfs/xfs_dquot_item.c | 8 + fs/xfs/xfs_iomap.c | 6 - fs/xfs/xfs_qm.c | 92 +++++------ fs/xfs/xfs_qm.h | 42 ++--- fs/xfs/xfs_qm_bhv.c | 20 +- fs/xfs/xfs_qm_syscalls.c | 231 +++++++++++++++------------- fs/xfs/xfs_quotaops.c | 12 + fs/xfs/xfs_trace.h | 160 ++++++++++++++++++- fs/xfs/xfs_trans_dquot.c | 329 ++++++++++++++++++++-------------------- 13 files changed, 744 insertions(+), 564 deletions(-)
