This small series of patches consists of: [PATCH 1/2 v2] scsi: target: tcmu: Optimize use of flush_dcache_page [PATCH 2/2 v2] scsi: target: tcmu: Fix crash in tcmu_flush_dcache_range Together with commit 8c4e0f212398 scsi: target: tcmu: Fix size in calls to tcmu_flush_dcache_range these patches fix crashes in tcmu on ARM. The first patch of this series already was sent some weeks ago as "PATCH RFC", since it was untested at that time. Meanwhile I added patch 2 of the series to fix the crash reported in: https://github.com/open-iscsi/tcmu-runner/issues/627 https://bugzilla.kernel.org/show_bug.cgi?id=208045 All three patches together were tested on ARM with kernel 4.19.118 and 5.7.2 (see github issue and bugzilla). --- v2: sent with a valid subject line.
