So I set out to switch that to another mechanism that would allow us to free up bytes. So this is an attempt to turn i_state from an unsigned long into an u32 using the individual bytes of i_state as addresses for the wait var event mechanism (Thanks to Linus for that idea.). This survives LTP, xfstests on various filesystems, and will-it-scale. * patches from https://lore.kernel.org/r/20240823-work-i_state-v3-1-5cd5fd207a57@kernel.org: inode: make i_state a u32 inode: port __I_LRU_ISOLATING to var event inode: port __I_NEW to var event inode: port __I_SYNC to var event fs: reorder i_state bits fs: add i_state helpers Link: https://lore.kernel.org/r/20240823-work-i_state-v3-1-5cd5fd207a57@kernel.org Signed-off-by: Christian Brauner --- 41b734352c1314807e2eea610023a9d9a340070f
