💅 VFS_QUOTACTL(9) — manipulate file system quotas 💅

okay so this is the VFS_QUOTACTL(9) page from the Kernel Developer's Manual, and it's literally about manipulating file system quotas. slay. 💖

✨ NAME ✨

VFS_QUOTACTL — manipulate file system quotas. periodt. 💅

🌸 SYNOPSIS 🌸

       #include <sys/param.h>
       #include <sys/mount.h>
       #include <sys/vnode.h>

       int
       VFS_QUOTACTL(struct mount *mp, int cmds, uid_t uid, void *arg,
           bool *mp_busy);

🦋 DESCRIPTION 🦋

okay so the whole point is: implement file system quotas. that's the vibe. ✨

The mp_busy argument is an input/output parameter. VFS_QUOTACTL() must be called with mp marked busy through vfs_busy(9) and *mp_busy set to true. like, no cap, that part is required. 🫶

Then the filesystem implementation of VFS_QUOTACTL() may unbusy mp using vfs_unbusy(9) prior to performing quota file I/O. If it does that, the implementation must set *mp_busy to false to indicate that the caller must not unbusy mp upon completion of VFS_QUOTACTL(). literally important, bestie — don't skip that. 💀

See quotactl(2) for a description of the remaining arguments. 👑
