π
ldm_validate_vmdb β bestie, it's page ldm_validate_vmdb(9), from the Kernel API Manual
okay so picture this: it's a kernel API man page, we're in section 9, and the whole entire job of this function is literally in the name. Let's get into it π
β¨ NAME β¨
ldm_validate_vmdb β it reads the VMDB and then validates it. That's it. That's the whole vibe. Read it, check it, slay π
πΈ SYNOPSIS πΈ
bool ldm_validate_vmdb (struct parsed_partitions *state , unsigned long
base , struct ldmdb *ldb );
notice the return type is bool, bestie β so you're getting a yes or a no, that's the whole tea π«Ά
π¦ ARGUMENTS π¦
stateβ the partition check state, and yeah it includes the device that's holding the LDM Database. like, this is the context bestie, the main character of the operation πbaseβ an offset intobdev, pointing at where the database lives. it's giving "your map pin for the database" πldbβ a cache of the database structures. iykyk, it's the stash spot π
π§ DESCRIPTION π§
So what actually happens? The function finds the vmdb of the LDM Database stored on bdev, and then returns the parsed information over in ldb. Find it, parse it, hand it back. genuinely iconic behavior β¨
no cap, that's the entire description β the man page doesn't overshare and honestly? respect π
β RETURN β
gorgeous, the original page just leaves this section blank. nothing here. no return value documented. not me pointing out the empty section ππ

like, the whole ldm friend group ate and left no crumbs π₯π
okay and for the cute sign-off: this page lives under ./block/partitions in the source tree, and it's dated October 2026, and the page itself is ldm_validate_vmdb(9). bye bestie, go validate something ππ§ββοΈ
