From 84a3c1576c5aade32170fae6c61d51bd2d16010f Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Tue, 2 Jul 2024 11:22:56 -0700 Subject: [PATCH] xfs: move xfs_extent_free_defer_add to xfs_extfree_item.c Move the code that adds the incore xfs_extent_free_item deferred work data to a transaction to live with the EFI log item code. This means that the allocator code no longer has to know about the inner workings of the EFI log items. As a consequence, we can get rid of the _{get,put}_group helpers. Signed-off-by: Darrick J.
