Subject: btrfs: use btrfs_chunk_max_errors() to replace tolerance calculation
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6dead96c1a1e091e78ee80a2484279c3861c60d8;p=linux.git

btrfs: use btrfs_chunk_max_errors() to replace tolerance calculation

In __btrfs_map_block() we have an assignment to @max_errors using
nr_parity_stripes().

Although it works for RAID56 it's confusing.  Replace it with
btrfs_chunk_max_errors().
