From 712bae96631852c1a1822ee4f57a08ccd843358b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 9 Feb 2025 05:43:50 +0100 Subject: xfs: generalize the freespace and reserved blocks handling xfs_{add,dec}_freecounter already handles the block and RT extent percpu counters, but it currently hardcodes the passed in counter. Add a freecounter abstraction that uses an enum to designate the counter and add wrappers that hide the actual percpu_counters. This will allow expanding the reserved block handling to the RT extent counter in the next step, and also prepares for adding yet another such counter that can share the code. Both these additions will be needed for the zoned allocator. Also switch the flooring of the frextents counter to 0 in statfs for the rthinherit case to a manual min_t call to match the handling of the fdblocks counter for normal file systems.
