From e5d7e4cbfa7c91a1da2aa43a2016bdb658ef564a Mon Sep 17 00:00:00 2001 From: Tian Yuchen Date: Sat, 13 Jun 2026 00:05:25 +0800 Subject: [PATCH] read-cache: move 'ce_mode_from_stat()' to 'read-cache.c' The ce_mode_from_stat() function is declared as a static inline function in 'read-cache.h'. As we want to migrate configuration variables, this helper function will need access to corresponding repository-specific configuration logic. Move the implementation to 'read-cache.c' to cleanly encapsulate its dependencies. Note that the 'extern int trust_executable_bit, has_symlinks;' line is discarded because it's not necessary when the function lives in "read-cache.c". At present, this change has no visible impact, but it is crucial for our future plans to pass in the repo context. Comment has been added whilst we are at it.
