gfs2_lookup_by_inum(9)

💖 NAME 💖

Welcome to gfs2_lookup_by_inum(9) from the Kernel API Manual, bestie! This page is literally about gfs2_lookup_by_inum — look up an inode by inode number. That’s the whole assignment, and it ate. ✨

🌸 SYNOPSIS 🌸

struct inode * gfs2_lookup_by_inum (struct gfs2_sbd *sdp , u64 no_addr ,
u64 no_formal_ino , unsigned int blktype );

🎀 ARGUMENTS 🎀

• sdp — The super block. Your main-character superblock, periodt. 👑
• no_addr — The inode number. The actual number you’re looking up, iykyk. 🔢
• no_formal_ino — The inode generation number (0 for any). So if you don’t care about the generation, pass 0 and let it be ✨.
• blktype — Requested block type (see gfs2_inode_lookup). This is the “what kind of block are we talking about” detail, and the manual points you at gfs2_inode_lookup for it. 🫶
