The regression was \nintroduced by commit 565180723294 in v4.12-rc1.\n\nThe regression is fixed by mainline commit \n07a191f762a7b8d0db13c38036380927116e29bb. This commit is in mailine\nas of v4.14-rc1. \n\nThe regression is that the ioctl DK_CAPI_VLUN_RESIZE can fail if the \nallocated vlun size is reduced from almost maximum capacity and then \nincreased again.\n\n\n== Fix ==\ncommit 07a191f762a7b8d0db13c38036380927116e29bb\nAuthor: Uma Krishnan \nDate: Fri Aug 25 17:18:12 2017 -0500\n\n scsi: cxlflash: Fix vlun resize failure in the shrink path\n\n\n== Regression Potential ==\nThis commit fixes a current regression and is limited to cxlflash.\n\n\n== Test Case ==\nA test kernel was built with this patch and tested by the original bug reporter.\nThe bug reporter states the test kernel resolved the bug.\n\n\nUma Krishnan (1):\n scsi: cxlflash: Fix vlun resize failure in the shrink path\n\n drivers/scsi/cxlflash/vlun.c | 6 +-----\n 1 file changed, 1 insertion(+), 5 deletions(-)"}
