4.10 compat - BIO flag changes and others
[bio] The req_op enum was changed to req_opf. Update the "Linux 4.8 API" autotools checks to use an int to determine whether the various REQ_OP values are defined. This should work properly on kernels >= 4.8. [bio] bio_set_op_attrs() is now an inline function and can't be detected with #ifdef. Add a configure check to determine whether bio_set_op_attrs() is defined. Move the local definition of it from vdev_disk.c to blkdev_compat.h for consistency with other related compability shims. [bio] The read/write flags and their modifiers, including WRITE_FLUSH, WRITE_FUA and WRITE_FLUSH_FUA have been removed from fs.h. Add the new bio_set_flush() compatibility wrapper to replace VDEV_WRITE_FLUSH_FUA and set the flags appropriately for each supported kernel version. [vfs] The generic_readlink() function has been made static. If .readlink in inode_operations is NULL, generic_readlink() is used. [zol typo] Completely unrelated to 4.10 compat, fix a typo in the check for REQ_OP_SECURE_ERASE so that the proper macro is defined: s/HAVE_REQ_OP_SECURE_DISCARD/HAVE_REQ_OP_SECURE_ERASE/ Reviewed-by: Brian Behlendorf <[email protected]> Reviewed-by: Chunwei Chen <[email protected]> Signed-off-by: Tim Chase <[email protected]> Closes #5499
