gfs2_ail1_start(9)
π gfs2_ail1_start β bestie's guide to kicking off that writeback π
Okay so real talk, this one lives in the Kernel API Manual (very official, very demure), and it's called gfs2_ail1_start. Say it with me: ail-one-start. It's giving "wake up, the AIL is not gonna flush itself." β¨
πΈ NAME πΈ
gfs2_ail1_start β starts writeback of all the ail1 entries. All of them. Not some. Not the cute ones. All. π
π SYNOPSIS π
void gfs2_ail1_start (struct gfs2_sbd *sdp );
That's the whole signature, bestie β no return value, it just goes and does the thing. Void, no cap. π«Ά
π¦ ARGUMENTS π¦
sdpβ the superblock. Like, the superblock. Hand it over and it's go time, okay? π

Buckle up, because this list is long and honestly iconic β the whole log.c friend group showed up. The kernel file is ./fs/gfs2/log.c and the whole squad is in there:

Go read them all, you know you want to. Main character energy, every single one. πβ¨
Lowkey a reminder: this is kernel-internal territory, so mind yoursdpβ it's literally the superblock and the function isvoid. No do-overs, no error return. π
And that's the whole page, bestie β short and slay. This cutie is filed under ./fs/gfs2 in the Kernel API Manual, dated October 2026, and it's gfs2_ail1_start(9) through and through. Go flush something. ππ
