💖 kunit_kstrdup_const(9) 💖

okay so this is a page from the Kernel API Manual, and it's about kunit_kstrdup_const — the function that conditionally duplicates a string into a test managed allocation. bestie, it's giving "I only duplicate when I absolutely have to" energy ✨

🎀 NAME 🎀

kunit_kstrdup_const — Conditionally duplicates a string into a test managed allocation. no cap, that's the whole name vibe 💅

✨ SYNOPSIS ✨

const char * kunit_kstrdup_const (struct kunit *test , const char *str , gfp_t gfp );

🌸 ARGUMENTS 🌸

  • test — The test context object. it's your test's little home base, the main character of the test world 🫶
  • str — The NULL-terminated string to duplicate. yes, the whole string, NULL-terminated and everything, not playing games 💖
  • gfp — flags passed to underlying kmalloc. those flags go straight to kmalloc, iykyk 🦋

🦋 DESCRIPTION 🦋

okay so here's the tea: it calls kunit_kstrdup only if str is not in the rodata section. that's the "conditionally" part, and it's lowkey important 👑

⚠️ bestie, listen: this thing must be freed with kunit_kfree_const — not kunit_kfree. do not mix them up, fr fr 😭

also see kstrdup_const and kunit_kmalloc_array for more information, because those are the related lore drops 📚✨
