gfs2_end_log_write_bh(9)

💖 NAME 💖

Okay so bestie, this is gfs2_end_log_write_bh(9) from the Kernel API Manual ✨ — and it’s literally the function that ends the log write of pagecache data with buffers. Periodt. 🎀

✨ SYNOPSIS ✨

       void gfs2_end_log_write_bh (struct gfs2_sbd *sdp , struct folio *folio ,
       size_t offset , size_t size , blk_status_t error );

🎀 ARGUMENTS 🎀

• sdp — The superblock 🫶
• folio — The folio 🌸
• offset — The first byte within the folio that completed ✨
• size — The number of bytes that completed 💫
• error — The i/o status 💀

🦋 DESCRIPTION 🦋

So what it does is find the relevant buffers, unlock them, and set the error flag according to the status of the i/o request. No cap. 🔥

You’ll see this used when the log is writing data that has an in-place version pinned in the pagecache. That’s the whole vibe check. 🧚
