ext4_get_stripe_size(9)

💖 NAME 💖

Welcome to the Kernel API Manual page for ext4_get_stripe_size(9), bestie! 🫶 The function is ext4_get_stripe_size, and its whole job is literally: get the stripe size. That's the mission. Periodt. 💅

✨ SYNOPSIS ✨

unsigned long ext4_get_stripe_size (struct ext4_sb_info *sbi );

🎀 ARGUMENTS 🎀

• sbi — in-memory super block info. That's the arg, bestie, and yes it's a struct ext4_sb_info * situation. 🧚

🌸 DESCRIPTION 🌸

okay so here's how the stripe size gets picked, no cap:

• If we have specified it via mount option, then use the mount option value. 💖
• If the value specified at mount time is greater than the blocks per group, use the super block value. ✨
• If the super block value is greater than blocks per group, return 0. 🫶
• The allocator needs it be less than blocks per group — that part is important, iykyk. 👑
