[ Upstream commit 0ea163a18b17f9e0f8350bb348ae69c4a376be66 ]
The names RESERVE and RELEASE are not only used in <scsi/scsi_proto.h> but also elsewhere in the kernel:
$ git grep -nHE 'define[[:blank:]]*(RESERVE|RELEASE)[[:blank:]]' drivers/input/joystick/walkera0701.c:13:#define RESERVE 20000 drivers/s390/char/tape_std.h:56:#define RELEASE 0xD4 /* 3420 NOP, 3480 REJECT */ drivers/s390/char/tape_std.h:58:#define RESERVE 0xF4 /* 3420 NOP, 3480 REJECT */
Additionally, while the names of the symbolic constants RESERVE_10 and RELEASE_10 include the command length, the command length is not included in the RESERVE and RELEASE names. Address both issues by renaming the RESERVE and RELEASE constants into RESERVE_6 and RELEASE_6 respectively.
