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?
Thanks,
