Hello, I have a question. man mount(8) says: max_inline=bytes Specify the maximum amount of space, in bytes, that can be inlined in a metadata B-tree leaf. The value is specified in bytes, optionally with a K, M, or G suffix, case insensitive. In practice, this value is limited by the root sector size, with some space unavailable due to leaf headers. For a 4k sectorsize, max inline data is ~3900 bytes. So, is the size of 4k-(size of leaf header) actually the maximum value of max_inline instead of 4095 for 4k sectorsize?
