Hi all, This is v3 of the allocbt block set aside fixup. The primary change in v3 is to filter out rmapbt blocks from the usage accounting. rmapbt blocks live in free space similar to allocbt blocks, but are managed appropriately via perag reservation and so should not be set aside from reservation requests. Brian v3: - Use a mount flag for easy detection of active perag reservation. - Filter rmapbt blocks from allocbt block accounting. v2: https://lore.kernel.org/linux-xfs/20210222152108.896178-1-bfoster@xxxxxxxxxx/ - Use an atomic counter instead of a percpu counter. v1: https://lore.kernel.org/linux-xfs/20210217132339.651020-1-bfoster@xxxxxxxxxx/ Brian Foster (2): xfs: set a mount flag when perag reservation is active xfs: set aside allocation btree blocks from block reservation fs/xfs/libxfs/xfs_ag_resv.c | 24 ++++++++++++++---------- fs/xfs/libxfs/xfs_alloc.c | 12 ++++++++++++ fs/xfs/libxfs/xfs_alloc_btree.c | 2 ++ fs/xfs/xfs_mount.c | 18 +++++++++++++++++- fs/xfs/xfs_mount.h | 7 +++++++ 5 files changed, 52 insertions(+), 11 deletions(-) -- 2.26.2
