The ZFS_ENTER/ZFS_EXIT/ZFS_VERFY_ZP macros should not be used in the Linux zpl_*.c source files. They return a positive error value which is correct for the common code, but not for the Linux specific kernel code which expects a negative return value. The ZPL_ENTER/ZPL_EXIT/ZPL_VERFY_ZP macros should be used instead. Furthermore, the ZPL_EXIT macro has been updated to not call the zfs_exit_fs() function. This prevents a possible deadlock which can occur when a snapshot is automatically unmounted because the zpl_show_devname() must never wait on in progress automatic snapshot unmounts.
