Darrick J. Wong 525488520a xfs: rmap btree requires more reserved free space ... Originally-From: Dave Chinner <dchinner@redhat.com> The rmap btree is allocated from the AGFL, which means we have to ensure ENOSPC is reported to userspace before we run out of free space in each AG. The last allocation in an AG can cause a full height rmap btree split, and that means we have to reserve at least this many blocks *in each AG* to be placed on the AGFL at ENOSPC. Update the various space calculation functions to handle this. Also, because the macros are now executing conditional code and are called quite frequently, convert them to functions that initialise variables in the struct xfs_mount, use the new variables everywhere and document the calculations better.
