Subject: reftable/stack: refactor function to gather table sizes
X-Git-Tag: v2.47.0-rc0~125^2~8
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ed7d2f4770659be207c0d512bceb337aa18c5527;p=thirdparty%2Fgit.git

reftable/stack: refactor function to gather table sizes

Refactor the function that gathers table sizes to be more idiomatic. For
one, use `REFTABLE_CALLOC_ARRAY()` instead of `reftable_calloc()`.
Second, avoid using an integer to iterate through the tables in the
reftable stack given that `stack_len` itself is using a `size_t`.
