In zpool_feature_init() in zfeature_common.c the hole_birth_deps array and the filesystem_limits_deps array are formatted with four space continuations, unlike the bookmarks_deps array and the large_blocks_deps array, which indent the elements with tabs, as is generally the custom for arrays throughout the codebase.

^Istatic spa_feature_t hole_birth_deps[] = { SPA_FEATURE_ENABLED_TXG,$
^I    SPA_FEATURE_NONE };$

and

^Istatic const spa_feature_t filesystem_limits_deps[] = {$
^I    SPA_FEATURE_EXTENSIBLE_DATASET,$
^I    SPA_FEATURE_NONE$
^I};$

vs.

^Istatic const spa_feature_t bookmarks_deps[] = {$
^I^ISPA_FEATURE_EXTENSIBLE_DATASET,$
^I^ISPA_FEATURE_NONE$
^I};$

and

^Istatic const spa_feature_t large_blocks_deps[] = {$
^I^ISPA_FEATURE_EXTENSIBLE_DATASET,$
^I^ISPA_FEATURE_NONE$
^I};$

Earlier in the file, there's also

^Istatic spa_feature_t nodeps[] = { SPA_FEATURE_NONE };$
