ubifs_log_post_commit(9)

🎀 ubifs_log_post_commit(9) 🎀

okay so this is a page straight out of the Kernel API Manual, and the star is ubifs_log_post_commit(9). it's giving "post-commit cleanup, but make it kernel." 💅

🌸 NAME 🌸

ubifs_log_post_commit — things to do after commit is completed. like, the after-party checklist for commit cleanup. 🫶

✨ SYNOPSIS ✨

int ubifs_log_post_commit (struct ubifs_info *c , int old_ltail_lnum );

🐚 ARGUMENTS 🐚

• c — the UBIFS file-system description object, aka the file-system's whole description vibe.
• old_ltail_lnum — the old log tail LEB number. literally that. 💫

🦋 DESCRIPTION 🦋

okay so the rule is: release the buds only after the commit is completed, because they must be unchanged if recovery is needed. do not rush the bud release, bestie. 🙈

same energy for the log LEBs: unmap them only after the commit is completed, because they may be needed for recovery. no early unmapping, no cap. 🔥

this function returns 0 on success and a negative error code on failure. that's the whole return situation. ⭐
