fs_context_for_submount(9)

okay bestie, welcome to fs_context_for_submount(9) from the Kernel API Manual — yes, that's the manual name, and yes, we're getting into it 💅✨

✨ NAME ✨

fs_context_for_submount — allocate a new fs_context for a submount. that's the whole name situation, and it's literally exactly what it sounds like 🫶

🌸 SYNOPSIS 🌸

struct fs_context * fs_context_for_submount (struct file_system_type
*type , struct dentry *reference );

🎀 ARGUMENTS 🎀

• type — file_system_type of the new context. it's giving "blueprint for the new context" energy 💅
• reference — reference dentry from which to copy relevant info. this is the reference dentry, and the relevant info gets copied from it, no cap 🦋

💖 DESCRIPTION 💖

okay so here's the vibe: this one allocates a new fs_context that's suitable for a submount. slay, iconic, periodt ✨

it also ensures that the fc->security object is inherited from reference — but only if needed, bestie. that's the important little detail, don't skip it 💜
