- Prevent that the allocation path wakes up kswapd. That's a long standing issue due to the GFP_ATOMIC allocation flag. As debug objects can be invoked from pretty much any context waking kswapd can end up in arbitrary lock chains versus the waitqueue lock. - Correct the explicit lockdep wait-type violation in debug_object_fill_pool(). -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmRzCBQTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoa8FD/sFaHGSVtNTYgkV75umETMWbx+nR0Sp Y/i62MswIWU/DWmD9IKaBxlHpBByHgopBAozDnUix6RfQvf8V/GSU6PWa9HAR2QH rYwQCN/2/e8yQNAFv+9AiYGzPU3fRI/z7rYgfhhiWoLjivMFUCXypjBG0BAiCBxC pYKZDMhBeySIUjtEL6xjcflA8XXKuLUPGy1WeKBxRgJeNvM0GlbifNXoy0JaXBso NK+1FOG7zm05r2RqZjN0rAVRrrdgA4JYygpYC8YmzePoFQVXLeUnlbjjW9uYX+hz MoLuVeF+rKk9NHNu3NoD4kFgrNp3NXAAAzH1MJwIADy9THtsyWAeEgyUkkie9aiX Oa8eSjpJQjUv5h+VRKpMhh2RAAAhCYDuX/QC2FLImLy+GRF3dMhsAmuYgKXN2kHa CFkM84vStMiMVxKhwtLpxVE7VOrxzXxbqMO65kMrCXYxK1SfKtEZr8FrORvUjU7G MmH+D9sB034nkCBU+oGMsMYAAzB4rLp5Cw9qqvwWLfJvWLcUoPxjgUV6hLR6mNXx 6+2133Tf68Fz4TgyEDN9XhQ7QEsKKGTTDMJ5JYolnrRe54sUJSsX+44khrbocSde WcEfcwhR+mjDDx0eVB2oT9bedxMf639mqPNn//EqJkzS4s+sECC8OiHbdvL3ArUq S92nrMxvyMB42Q== =7B4m -----END PGP SIGNATURE----- Merge tag 'core-debugobjects-2023-05-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull debugobjects fixes from Thomas Gleixner: "Two fixes for debugobjects: - Prevent the allocation path from waking up kswapd.
