security_sb_mnt_opts_compat(9)

💖 NAME 💖

okay so this is the manual page for security_sb_mnt_opts_compat(9) — a Kernel API Manual entry, and it’s literally about checking if new mount options are allowed. 🎀

✨ SYNOPSIS ✨

int security_sb_mnt_opts_compat (struct super_block *sb , void *mnt_opts
);

🦋 ARGUMENTS 🦋

• sb — filesystem superblock. iykyk, it’s the superblock we’re checking against.
• mnt_opts — new mount options. the fresh options wanting in.

🌸 DESCRIPTION 🌸

so the function determines if the new mount options in mnt_opts are allowed, given the existing mounted filesystem at sb. sb is the superblock being compared. no cap, that’s the whole vibe check.

💅 RETURN 💅

Returns 0 if options are compatible. periodt. ✨
