Hi Martin, This patch series includes the following changes: - Fix a deadlock in the UFS error handler. - Add polling support in the UFS driver. - Several smaller fixes for the UFS driver. Please consider these UFS driver kernel patches for kernel v5.17. Thanks, Bart. Changes compared to v3: - Dropped patch "scsi: core: Fix a race between scsi_done() and scsi_times_out()" since the conversation around that patch is still ongoing. - Added patch "scsi: ufs: Remove hba->cmd_queue". - Modified patch "scsi: ufs: Optimize the command queueing code". Changes compared to v2: - Dropped SCSI core patches that add support for internal commands. - Reworked patch "Fix a deadlock in the error handler" such that it uses a reserved tag as proposed by Adrian. - Split patch "ufs: Introduce ufshcd_release_scsi_cmd()" into two patches. Changes compared to v1: - Add internal command support to the SCSI core. - Reworked patch "ufs: Optimize the command queueing code".
