From: Theodore Ts'o Date: Sat, 14 Aug 2021 14:39:13 +0000 (-0400) Subject: mke2fs: warn that bigalloc is experimental only for large cluster sizes X-Git-Tag: v1.46.4~24 X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=e732c9fa1c6a8089c94639de559cf2cf236644ba;p=tools%2Fe2fsprogs.git mke2fs: warn that bigalloc is experimental only for large cluster sizes Since we have done a lot of testing with a cluster size equal to 64k (or 16 times the default 4k block size), mke2fs will only warn for bigalloc file systems where the cluster size is greater than 16 times the block size.
