security_sb_statfs(9)
π NAME π
okay bestie, this is security_sb_statfs(9) from the Kernel API Manual β yes, thatβs the manual name, and this page is literally a lil icon. Its whole job? Checking if accessing fs stats is allowed. slay.
β¨ SYNOPSIS β¨
int security_sb_statfs (struct dentry *dentry );
π ARGUMENTS π
dentryβ the superblock handle, aka your VIP pass to the fs. donβt lose it bestie.
πΈ DESCRIPTION πΈ
So this function is the vibe check before anyone gets to obtain filesystem statistics for the mnt mountpoint. permission first, stats second, periodt.
And dentry? Itβs a handle on the superblock for the filesystem. Thatβs the whole lore. π
π¦ RETURN π¦
Returns 0 if permission is granted.
Thatβs the entire return story β no secret extra codes mentioned here, no cap.
