gfs2_quota_check(9)

💖 NAME 💖

Okay bestie, we're looking at gfs2_quota_check(9) from the Kernel API Manual, and it does exactly what it says: check if allocating new blocks will exceed quota. Periodt. ✨

🦋 SYNOPSIS 🦋

int gfs2_quota_check (struct gfs2_inode *ip , kuid_t uid , kgid_t gid ,
       struct gfs2_alloc_parms *ap );

🌸 ARGUMENTS 🌸

• ip — the inode for which this check is being performed. Like, whose vibe are we quota-checking? 👀
• uid — the uid to check against.
• gid — the gid to check against.
• ap — the allocation parameters. ap->target contains the requested blocks. ap->min_target, if set, contains the minimum blks requested.

🎀 RETURN 🎀

0 on success. 🫶

And the math is literally:

min_req = ap->min_target ? ap->min_target : ap->target;

Quota must allow at least min_req blks for success, and ap->allowed is set to the number of blocks allowed. Slay. 💅

🔥 DESCRIPTION 🔥

-EDQUOT otherwise, quota violation. ap->allowed is set to number of blocks available.

Cute little sign-off: this page is from source/version ./fs/gfs2, dated October 2026, and yes, it's still gfs2_quota_check(9). 💜🌈
